Recombinational repair of DNA damage in Escherichia coli and Bacteriophage lambda

Article Abstract:

Recombinational repair of DNA damage in Bacteriophage lambda and Escherichia coli are discussed to consolidate genetic data on homologous recombination physical data on DNA damage/repair and biochemical data on recombinational enzymes with a different approach to suggest new areas for experimentation. The approach is from the perspective that the main role of the homologous recombination system in E. coli is to repair lesions associated with DNA replication of damaged template DNA.

Cytopathogenesis and inhibition of host gene expression by RNA viruses

Article Abstract:

The physiological and molecular aspects of viral cytopathogenesis, a by-product of host antiviral response and its countering by virus devised mechanisms, are discussed. Several models are proposed to explain the latter by incorporating transcription, RNA processing and transport, and translation as revealed by picornaviruses, influenza viruses, and rhabdoviruses

Coupling of flagellar gene expression to flagellar assembly in Salmonella enterica serovar Typhimurium and Escherichia coli

Article Abstract:

The bacterial flagellar structures and their assembly are regulated by over 50 genes and there exists an efficient coupling mechanism to coordinate their assembly and function. Data reveal that the flagellar genes are transcriptionally regulated via interwoven regulatory pathways involving molecular complexes such as regulons.
