For a cell to divide, all the DNA inside the cell (the genome) must first be copied, in a process called DNA replication.

The exact moment DNA starts to unravel has been seen by scientists for the first time, exposing a chemical process that is essential for DNA to be the molecule that codes for all life.

In a new study reported in Frontiers in Cell and Developmental Biology, scientists used a bacterial model to show that in zero gravity, the enzymes that copy DNA are not as accurate as they are under ...

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 ...

The whole process of DNA replication, in human cells, takes about eight hours. There is still plenty to be worked out. For one thing, the DNA that’s being copied is not a naked double helix.

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

It functions like a guardian for the DNA replication process, and it has an analog in humans called CHEK1. As a checkpoint, the gene ensures the DNA is smoothly copied before cell division.

The cell controls the start of DNA replication in a two-step process. The whole goal of the process is to control the actions of a crucial enzyme—called a helicase—that unwinds the DNA double ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a study published in Nature Communications.
