Replication Fork Reversal after Replication–Transcription Collision
Replication fork arrest is a recognized source of genetic instability, and transcription is one of the most prominent causes of replication impediment. We analyze here the requirement for recombination proteins in Escherichia coli when replication-transcription head-on collisions are induced at a specific site by the inversion of a highly expressed ribosomal operon (rrn). RecBC is the only reco...
متن کاملTranscription factors in DNA replication.
Accumulating evidence suggests the involvement of transcription factors in the regulation of DNA replication in eukaryotic cells. Almost all eukaryotic DNA viruses contain binding sites for transcription factors which function as auxiliary elements for DNA replication initiation at replication origins, and, indeed, the binding of transcription factors to these elements has been shown to stimula...
متن کاملPorcine circovirus: transcription and DNA replication.
This review summarizes the molecular studies pertaining to porcine circovirus (PCV) transcription and DNA replication. The genome of PCV is circular, single-stranded DNA and contains 1759-1768 nucleotides. Both the genome-strand (packaged in the virus particle) and the complementary-strand (synthesized in the new host) encode viral proteins. Among a multitude of RNAs synthesized by alternate sp...
متن کاملTranscription and replication of influenza virus RNA.
The Influenza viruses are among the most dangerous human pathogens, since they have a wide animal reservoir and re-emerge continuously in the human population. They constitute a collection of highly variable pathogens that cause respiratory infections in man. Influenza type A viruses contain a segmented genome composed by 8 RNA molecules of negative polarity. Each one replicates and transcribe ...
متن کاملPolymerase Stalling during Replication, Transcription and Translation
Replication, transcription, and translation stress all lead to stalling of their respective polymerases (DNA polymerase, RNA polymerase, and the ribosome), and the cell must respond to these events in order to preserve macromolecular integrity. In response to replication stress such as DNA damage, the cell activates a checkpoint and promotes repair or bypass at the lesion. Transcriptional stres...
