Researchers are embarking on the RNA equivalent of the Human Genome Project, including sequencing all the chemical ...

Extremely short, or tiny, fragments of RNA - working copies of our genetic code - play a critical role in keeping the immune system in check ...

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

A surprising amount of the DNA sequence in the genes of humans and other higher organisms ends up on the cutting-room floor, so to speak, spliced out by the cellular machinery that turns genetic code ...

Although the participation of spliceosomes is almost always required for intron removal, a few types of genes have self-splicing RNA introns.

The original version of this story appeared in Quanta Magazine. For a molecule of RNA, the world is a dangerous place. Unlike DNA, which can persist for millions of years in its remarkably stable, ...

The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

A newly revealed “aging cliff” in sperm RNA marks a conserved molecular transition from youth to later life, offering fresh insight into how a father’s age may influence the earliest stages of ...
