Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

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 ageing, cancer, ...

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 ...

If parent cells and their daughter cells are to share a stable identity, parent cells must divide—and replicate their DNA—while ensuring that their histones are distributed properly to their daughter ...

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

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

The herpesvirus can manipulate our DNA with far more precision than previously thought. The virus condenses and changes the shape of our genetic material to hijack the host genes needed for ...
