In the prokaryotic bacterium E. coli, replication can occur at a rate of 1,000 nucleotides per second. In comparison, eukaryotic human DNA replicates at a rate of 50 nucleotides per second.

This important study presents compelling observational data supporting a role for transcription and polysome accumulation in the separation of newly replicated bacterial chromosomes. The study is ...

It has been determined that prokaryotic DNA replication occurs at a rate of 1,000 nucleotides per second, and prokaryotic transcription occurs at a rate of about 40 nucleotides per second (Lewin ...

coli has a circular chromosome, but replication doesn’t occur clockwise around the chromosome ... multiple origins of replication on each chromosome, and some regions of the DNA are more tightly ...

coli bacteriophages T4, T6, T7, and T3, encode their own ATP-dependent DNA ligases. ATP-dependent DNA ligases are also encoded by eukaryotic DNA viruses that conduct some or all of their replication ...

She has studied how the pathogenic bacterium Escherichia coli reacts when exposed to ... When the bacterium is about to divide, it ensures that DNA replication occurs in a safe and orderly manner.

How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...

A team has unearthed new findings about what happens during the minutes and hours after a cell divides, expanding our understanding of human biology -- and potentially leading to better medicines.

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

coli (intestinal bacterium), concluding ... "Mutations occur either in the process of replication—copying DNA, or when ...

1). We have used replication systems reconstituted with purified E. coli replication proteins and DNA templates carrying a single, site-specific cyclopyrimidine dimer (CPD) to analyze the events that ...
