A research review favors migration between 20,000 and 14,000 years ago for ancestors of most living Indigenous Americans.

New migration estimate: Genetic evidence points to Indigenous ancestors arriving no earlier than 21,000 years ago, near the end of the Last Glacial Maximum. Debate continues: Conflicting ...

By sequencing DNA from ancient cave remains, museum specimens, and living bats, researchers have reconstructed more than two ...

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 ...

Genetic features known as transposons make up a large portion of many mammalian genomes, including humans', and they are now known to play a variety of roles. Some transposable elements (TEs) could be ...

Repetitive sequences make extrachromosomal DNA vulnerable to breaks, which could be exploited for therapy — but might also promote tumour evolution.
