Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now ...

The DNA of human cells consists of a sequence of about 3.1 billion building blocks. Cells go to great lengths to maintain the ...

"We recorded multiple snapshots showing how this molecular motor methodically separates the DNA double helix. It's like a molecular-scale zipper in action and while scientists have long known that ...

It resembles a DNA double helix and is made of intertwined stainless steel and glass. It is built 280 meters across Marina Bay and serves as a pedestrian walkway.

Interstrand crosslinks, DNA-protein crosslinks, DNA secondary structures, and regions of active transcription interfere with helix unwinding and DNA synthesis. Some barriers are naturally occurring ...

All modern humans share DNA from two ancient populations that split 1.5 million years ago and reunited through interbreeding about 300,000 years ago. The genetic mixture is approximately 80% from one ...

and then twists the DNA helix to make the damage accessible. XPC then calls in other repair proteins to help initiate the second stage, called damage verification, or lesion scanning, according to ...

The South African Police Service (SAPS) has again faced a large backlog of DNA samples, which threatened the criminal justice system. The backlog has once again spiralled out of control and now ...
