A cell copies all six billion letters of its DNA, gears up to split, and then simply… doesn’t. It sits there, swollen with ...

It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, ...

Bacterial DNA replication is a highly coordinated process that ensures faithful genome duplication and cell division. Replication initiates at a single chromosomal origin (oriC) where multiple copies ...

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 at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from ...

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

When it comes to cancer, tumor suppressor genes are usually thought of as the "good guys." These genes make proteins that ...

Structural biologists at the University of Wisconsin-Madison today published cryo-electron microscopy structures of the complete bacterial DNA replication restart complex — a molecular machine that le ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...
