Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Researchers have gained a clearer insight into how common alterations to the structure of DNA affect the process of DNA replication. These structural changes can put a stop to replication, causing ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist ...

As genome editing therapies move through clinical trials to regulatory approval, scientists continue the quest for the holy ...

DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...
