While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means ...

His team set about using cryo-EM to examine how RNAP remains clamped to DNA after transcription termination, and how RapA interacts with it. They chose negatively supercoiled DNA—an underwound ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 ...

They applied the new method to more than 1,500 European genomes (a person's complete set of DNA) from people who lived primarily during the first millennium AD (year 1 to 1000), encompassing the ...

As she worked at her computer, the results revealed the sample she was examining contained human DNA. There was nothing so unusual about that in itself: at the time, the ancient DNA (aDNA ...
