When these pathways are activated, DNA replication is suppressed at sites in the genome called origins; at the same time, the progression of DNA replication forks also slows down. Replication forks, ...

Forks colliding: How DNA breaks during re-replication Date: June 4, 2015 Source: Whitehead Institute for Biomedical Research Summary: Leveraging a novel system designed to examine the double ...

This forms two replication forks that move along the DNA, replicating as they go. Primer Synthesis. Primer synthesis marks the beginning of the actual synthesis of the new DNA molecule.

DNA replication and repair are critical processes that ensure the correct genetic material of a biological system is carried on. DNA continually undergoes a process of replication and division and ...

A University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. This new structural and ...

DNA Replication: Within the nucleus of every cell are long strings of DNA, the code that holds all the information needed to make and control every cell within a living organism.
