Scientists have uncovered an unexpected genetic shift that may explain how animals with backbones first emerged and became so diverse.

Duplicated genes that appear in every branch of the tree of life can provide us with insight into the evolution that occurred ...

Life runs on instructions you never see. Every cell reads DNA, turns that message into RNA, and then builds proteins that ...

Genetic ancestry plays a key role in determining the behavior of head and neck tumors and may help explain why African-American patients survive for half as long as their counterparts of European ...

For years, the standard line in longevity research was that genes only nudged the odds of a long life while lifestyle and ...

All life on Earth shares a common ancestor that lived roughly four billion years ago. This so-called "last universal common ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

DNA can be thought of as a vast library that stores all genetic information. Cells do not use this information all at once. Instead, they copy only the necessary parts into RNA, which is then used to ...

A duplicated gene evolved into a switch that determines sex in frogs, revealing how evolution can safely reshape critical ...

New twin‑study research finds that, after removing deaths from accidents and infections, genes account for about 50% of human ...

In 1933, geneticist Thomas Hunt Morgan won the Nobel Prize in Physiology or Medicine for demonstrating that genes exist on chromosomes, which are passed down from parent to offspring. Ninety-one years ...
