Uracil is a nucleobase, one of four (along with adenine, guanine and cytosine) that make up ribonucleic acid, or RNA, which is used by cells to communicate genetic information.

On Tuesday, Japanese scientists revealed they discovered within the Ryugu samples the presence of uracil, a component that’s critical to the makeup of RNA.

Uracil can also be involved in mutations, which are changes in the genetic material. One type of mutation, called a point mutation, occurs when a single nucleotide is changed. In RNA, a point mutation ...

Uracil and other organic molecules have previously been found in these meteorites, but there has been no way to rule out the possibility that some of the molecules had a terrestrial origin.

Organic molecules, including uracil and niacin, have been detected in samples collected by Japan’s Hayabusa2 mission from the near-Earth asteroid Ryugu. Uracil is a component of RNA while niacin ...

The uracil mustard was given orally in the form of 1-mg. or 5-mg. capsules. In 30 patients the initial dosage administered was 10 mg. per day (divided in 2 doses) for three days.

Researchers just announced the discovery of the nucleobase uracil—one of the building blocks of RNA—in a sample from the asteroid Ryugu. Here's what it means.
