recombinant DNA researchave impr^-ci rapidly,
but still lag Western state-of-the-art by several years. The scope of Soviet recombinant DNA research is limited because of the small number of qualified molecular geneticists to initiate research projectshortage of adequately equipped laboratories. The Soviet research enjoys high-level support,ontinuing high interest in the field is expected.
Taking advantage of continuing access to virtually all advanced Western recombinant DNA research which is neither classified nor proprietary, the Soviets should be able to establish within two to fiveasic research program using recombinant techniques that is of moderate size and high quality; it is improbable, however, that they will challenge the leadership of the best Western laboratories.
Soviet recombinant DNA research appears to be directed primarily toward agricultural, biomedical, and commercial applications. The Soviets probably will experience difficulties in adapting laboratory techniques to achieve these goals because of the still limited scope of their program and inadequate Support technologies in the biomedical
military-sponsored recombinant DNA work has been reported, but it is improbable that this work is directed toward or is capable of achieving significant biological warfare applications.

The rectnl development of recombinant DNA technology has raised concern lhat the USSR will acquire recombinant capabilities from the West as well as through its own efforts and use them tu thc disadvantage of the United States. This paper assesses current Soviet research capabilities, likely trends in the scope and quality of future Soviet research, the importance to the Soviets of the various means through which they can obtain detailed information about advanced Western recombinant research techniques, and Ihc likelihood that the Soviets will derive meaningful benefits fromDNA techniques.j

Soviet Recombinant DNA Research: Status and Trends
The term "genetic engineering" often is used interchangeably with the term "recombinantut the two are not synonymous. Genetic engineering refers to advanced basic and applied research techniques that have evolved frombiology and related research ingenetics and cell physiology. Theseimpart the capability lo modify orpurposefully the genetic characteristics or the developmental sequences of cell* or organ* isms at the molecular or cellular level. Included within this restricted definition of geneticare such things as "test tube babies" as well as more exotic research directed toward producing hybrid (chimeric) organisms orhuman beings or other mammals. At times genetic engineering has been used somewhat inappropriately to refer to all applied genetic research, including such traditional areas ofas livestock breeding and developing new hybrid varieties of plants, ;
Recombinant DNA encompasses only onearea of genetic engineering; namely, Bpecific biochemical and microbiologicalto alter,elatively controlled and reasonably predictable manner, the molecules that encode the genetic characteristics of an organism, and to introduce specifically selectednew tu theanset of genetic Instructions.
The specific molecular manipulations that are made and the exact methods used to make them can vary widely from one recombinant DNA experiment to another. The basic process,usually involves the Initial isolation or synthesispecific set of chemically identical nucleic acid molecules (usuallyolecules are thenbonded orfccomblnnnt
specially prepared vectoia (carriers) that usually are plasmids. bacteriophages, or other virus-like infectious entities that can self-replicate in appropriate host cells. After the bonding has been completed, the modifiedcan be inserted into bacteria or other cells that lave been prepared biochemically to accept them. If the vectors have been "constructed" appropriately, tbe piece of initially selected DNA can give the recipientew geneticFor Instance, the host cell might be given the capability to synthesize an enzyme that il previously could not make. This enzyme in turn could permit the host cell to metabolize aundigestible food source or to become Immune to some previously lethal drug orAlternatively, these same procedures can be used to study the chemical structure (or other molecular biological properties) of the inserted DNA. In this case, the host cell is simply allowed to propagate, which in turn causes many copies of the inserted DNA sequence to be made (cloned) also. These cloned sequences then can be isolated biochemically in quantities andnot possible by other means.
: Starvf of Soviet Recombinant DNA Research
1 Most Soviet studies using recombinant DNA techniques have been initiated only within the past few years. The Soviets have advanced their recombinant DNA capabilities primarily byto exploit experimental techniquesin the West (mostly in the United States) and by acquiring specially modifiedand host cell-lines from Western colleagues. These Soviet efforts to obtain Westerntechnologies appear to be continuing. [I,. 41
Soviet recombinant research is conducted by competent scientists, but has not progressed suf-
ficicntly for their researchers lo hive specialized knowledge to offer in return for advancedtechniques obtained from the West. They have contributed somewhat toyew methods to change the chemical recognition specificity of several enzymes (restrictases) used during some recombinant]
Thc Sovirts are believed to have only aboul five research groups that have demonstrated reasonably advanced recombinant capabilities (seend these Soviet groups ere from one to two years behind most of the several hundred US groups. The best Soviet research

The missions of these institutes included conducting research directed toward possibleapplications of recombinantonetheless, the Soviet military is not known to be using recombinant tcchni,or biological warfare (BW) purposes. Military-funded Soviet research instituies probably would use recombinant techniques for basic biomedical studies. For instance, projects could be oriented toward developing prophylactic agents suitable for use against infectious diseases. Such work probably would include the development ofvaccines for dysentery and typhoid fever, as well as vaccines for more exotic viralas those in Africa.
Soviet military-sponsored recombinant DNA research nrobably is not advanced technically.

It is not yet clear if recombinant techniques can be useful for BW research. Some US experts have argued that traditional techniques toBW agents arc more cost effective. Also, they felt lhat recombinant techniques probably could not be used to enhance meaningfully theof existing agents or toew "super"] Others have argued that the developmentsuper" bug is not necessary. The simple transfer of debilitating diseases, such as dysentery, to normally nonpathogenicsuchommon inhabitant of the human digestivebe sufficient to make identification of the causative agent and effective treatment of the induced pathologies extremely difficult. The counter argument to this has been that several decades of testing uiually is required to understand sufficiently the ecology and epidemiology of any new "bug" to sanction its useredictable military weapon.
Two basic categories of Western recombinant DNA information which are potentially relevant
to the Soviet military include: recombinantinvolving the transfer of factors that arc pelbogenic to man or that can increaseovel way the virulence of organisms infectious to humans; and procedures and equipment used lo support biologically hazardous recombinant DNA research.
The conduct of biologically hazardousinvolves traditional microbiological safely equipment and techniques that have been used in the biomedical handling and study of pathogenic organisms. Although some of the techniques for constructing advanced protection equipment (or "high containment" facilities in general) have become somewhat of an art, most of theand equipment designs have beenopenly. Much of the equipment iscommercially.
Recombinant DNA research involving factors pathogenic lo humans has been severely limited by the safety restrictions governing moslresearch. Thus, little information currently isubstantial amount of information should become available in the future as the number of high containmentthat permit experiments to be undertakenSuch information probably will be made available in the open literature.

The Soviets can acquire information useful to their recombinant DNA research effortsumber of sources. Virtually all US and most foreign research data and techniques have been published or are being prepared for publication in the open literature. Even the detailsrocedure recently submitted for US patent rights have been published] Two of the coauthors on this patented research project are now conducting research in West European laboratories.
Most advanced Western scientists arc free lo communicate research activities and procedures to foreign scientists both through writtenand al internationalJ The distribution of samples and supplies of newly developed vectors or host cells also has been left
to the discretion of the scientists possessing them, for non-Communist nations have [neitherorced regula ions that exist (such asf the US unilateral Commodity Control List) nor issued guidelines concerning theof research information or specimen transfers.
Although the US remains at the forefront of recombinant research worldwide, many foreign researchers, particularly ir Europe are capable of providing, and in some cases have provided, the Soviets with experimental supplies that were both adequate and as good as could have been obtained from US sources (seeany of the specialized enzymes also are now available commercially from numerous Western suppliers.

Soviet Capability-mi.Ota Foreign Recombinant Technk-uo*
T'le Soviets traditionally have had littleat converting microbiological andlaboratory techniques into usefuloperations. This probably will be the case with Soviet attempts lo apply recombinant DNA techniques. For instance, the Soviets arc considered to be relatively unsophisticated in several fields of biological research (such as the genetic manipulation of plant cell proloplasis in tissue culture) that probably will be needed in conjunction with recombinant techniques to achieve certain industrial or aariculturalFurthermore, despite the extremely nigh quality of Soviet organic chemists, fewhigh-quality laboratory reagents have been produced in thet appears improbable thai the use of recombinantsuddenly would enable Soviet biochemical or pharmaceutical industries either to develop or toufficiently large number of high-quality products to compete meaningfully with Western Industries. Soviet capabilities to apply recombinant DNA techniques to military-oriented research projects should face similar constraints.
Despite ths problems anticipated with Sovici attempts to adapt recombinant techniques to commercial uses, over the next two to five yea's they should be able toidrc of competent, basic research scientists fully trained in the use of advanced recombinant DNAThe ready availability of Westerndata already has saved Soviet researchers several years of developmental research effort. The rate at which the Soviets arc able toimproving their recombinant capabilities should remainon the acquisition of advonccd Western work for atew years more.

The research efforts of these groups appear unlikely to be hampered byenforced research restrictions designed lolhat research activities do not pose inadver-tant health hazards, despite the fact lhat research guidelines have been adoptedhe Soviets are thus expected to attain recombinant research capabilitiesto many Western laboratories, but they arc not likely to challenge seriously the leadership of the most advanced Western laboratories.
If Soviet access to Western expertise were suddenly to be restricted, it would delayby as much as an additional fiveestablishmentophisticatedresearch program. Sufficient capabilities have been established by thc Soviets already, however, for them to piocccd on their own. Currently, Soviet recombinant DNA research dependence on the West probably is most tightly linked to Western biochemical supplies andlaboratoryas ultrnccn-trifuges and scintillationlthough inconvenienced by thc need to anticipate laboratory supply requirements atear in advance because of the long lag time frequently experienced between requesting and receiving material, Soviet biomedical ic* search would be dealt an even greater blow if only Soviet biochemicali and precisionwere available.

Information of this type has permitted thewell as new laboratory groupsselectprocedures previously demonstrated lo be appropriate and to avoid proceduresfound to present difficulties or to be less efficient than otherubstantialof these types of generally applicabletechniques should continue to appear inWestern literature for the ncxl year or two. Thereafter, an increasingly greater portion of new recombinant techniques probably willrelatively project specific.
As Soviet laboratories begin inc:ca>ingly to narrow the focus of their research projects,they probably will establish unique projects of their own choosing rather than simplyor attempting to compete with advanced Western work. At this point lhe relativeof personal contacts should increaseto the information available in 'he open literature because the experimental problems that are encountered during specialized research projects usually are best solved through informal consultations with colleagues, and because ihc West will continue toubstantiallynumber of (echnially advanced scientists than will the USSR.

Currently, however, formal research exchanges probablyore useful form of personal contact to the Soviets.
