DNA replication was identified in the late 1950s, but since then researchers across the globe have come up short trying to understand exactly how this process was regulated. Now they know.

Replication is the process of copying DNA molecule and transcription is the process of RNA synthesis, both using DNA as a template.

A cell can’t do this if it doesn’t replicate its DNA in the right place, at the right time, and in the right manner, while simultaneously avoiding over-replication.” ...

DNA, which has a double-helix structure, can have many genetic mutations and variations. Credit: NIH When cells in the human body divide, they must first make accurate copies of their DNA.

However, exactly how the DNA “opening” phase is initiated has remained a mystery. Now for the first time, researchers show that DNA replication in mammalian cells initiates after a vise-like ring of ...

DNA over-replication is a phenomenon that can have devastating consequences for proliferating cells. When parts of the genome are duplicated more than once, cells suffer from 'genomic instability ...

Researchers at Colorado State University have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach ...
