DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

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 ...

A new fluorescent sensor lets scientists track DNA damage and repair in real time inside living cells, advancing cancer research, drug testing and ageing biology. (Nanowerk News) Cancer research, drug ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

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 ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

This footage shows the fluorescent sensors in action inside a living cell. They appear as bright green spots the moment they bind to sites of DNA damage. Cancer research, drug safety testing and ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division - a discovery that could lead to new cancer therapies, according ...
