Asteroids, small airless bodies within the inner solar system, are theorized to have contributed water and chemical building blocks of life to Earth billions of years ago. Although meteorites on Earth ...

Scientists detected all five nucleobases -- building blocks of DNA and RNA -- in samples returned from asteroid Bennu by NASA's OSIRIS-REx mission.

Are we extraterrestrial? Something was recently discovered by NASA on a near-Earth asteroid. They are Organic Molecules On ...

Japanese collaborators detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid ...

Samples of Bennu were brought back to Earth by NASA’s OSIRIS-REx spacecraft in 2023. Now, a pair of newly published papers ...

Nucleic acid bases are essential molecules for the structure of DNA and RNA ... There are four main nucleic acid bases: adenine, thymine, cytosine, and guanine, with uracil as an additional one. These ...

The sugar molecule in DNA molecules is β-D-2 deoxyribose. Here thymine (T) is present instead of uracil (U). The helical structure of DNA is double-stranded. DNA forms the chemical basis of heredity.

Persistent population structure thus suggests a lower effective migration rate ... Libraries were partially treated with uracil-DNA glycosylase (UDG) and screened for ancient DNA damage patterns, high ...
