When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, ...
DNA replication dynamics in cells from higher eukaryotes follows very complex but highly efficient mechanisms. However, the principles behind initiation of potential replication origins and emergence ...
Termination of DNA replication occurs when two replication forks meet on the same stretch of DNA, during which the following events occur, although not necessarily in this order: forks converge until ...
Scientists have uncovered how DnaA, the master key to DNA replication, opens the door to bacterial growth. This breakthroughpaves the way for new antibiotics to combat the rising tide of antibiotic ...
Extracts of the DNA initiation-defective mutant Escherichia coli dnaB252 are inactive in a dnaB complementation assay but yield a ribonucleoside triphosphatase activity of native molecular weight of ...
Using single-molecule DNA nanomanipulation, we show that abortive initiation involves DNA "scrunching"--in which RNA polymerase (RNAP) remains stationary and unwinds and pulls downstream DNA into ...
Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a ...
