Epigenetic regulation of DNA replication studied by super resolution microscopy - Alexei Budco - Master's Thesis - Biology - Genetics / Gene Technology - Publish your bachelor's or master's thesis, dissertation, term paper or essay Electron microscopy analyses of replicating chloroplast molecules earlier predicted bidirectional Cairns replication as the prevalent mechanism, perhaps followed by rounds of a rolling circle mechanism. Single-stranded DNA are coated with replication protein A (RPA) (light pink). Polα bound to a primase, initiates lagging strand synthesis (blue line), herein an RNA primer is first elongated by Polα and then by Polδ. The distribution and strength of DNA-binding sites about the octamer surface distorts the DNA within the nucleosome core. Once inside the host bacterium, replication of the [+] ssDNA genome proceeds via negative sense DNA intermediate. This is done as the phage genome supercoils and the secondary structure formed by such supercoiling attracts a primosome…

These results suggest that the 5′→3′ exonuclease activity of DNA polymerase I plays a major role in removal of primer RNA and that RNase H functions in an auxiliary role, excising the 5′-portion of longer primers. The rnh mutant supports replication of ColE1-type plasmids.

The monomers activate initiation of replication by binding to directly repeated DNA sequences (14, 16), whereas the dimers repress repA transcription by binding to an inversely repeated DNA operator (19, 16). DNA polymerase I (or Pol I) is an enzyme that participates in the process of prokaryotic DNA replication. Discovered by Arthur Kornberg in 1956, it was the first known DNA polymerase (and the first known of any kind of polymerase). It was originally isolated by Thomas Kornberg in 1970, and characterized over the next few years. The in vivo functionality of Pol II is under debate, yet consensus shows that Pol II is primarily involved as a backup enzyme in prokaryotic…
