Scientists have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission ...

In addition to the five nitrogenous bases—adenine, guanine, cytosine, thymine and uracil—required for building DNA and RNA, ...

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

This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...

Nucleotides are the combination of a five-carbon sugar, ribose, along with a phosphate group and one of five possible ...

Importantly they also discovered all five nitrogenous bases — adenine, guanine, cytosine, thymine, and uracil — that are ...

Both uracil and thymine pair with adenine ... In RNA, a point mutation can involve the substitution of uracil with another nucleobase, such as cytosine (C) or guanine (G). These mutations can ...

Scientists have found all five nucelobases alongisde minerals essential for life as we know it on the potentially hazardous ...

Nucleobases: The building blocks of nucleic acids (DNA and RNA), which include purines (adenine, guanine) and pyrimidines (cytosine, thymine, uracil). RNA world hypothesis: A theory suggesting ...

In 1992, researchers found that the amination reaction of sodium bisulfite with unmethylated cytosine is different than the reaction of sodium bisulfite with 5mC. Because of this difference, ...

Study indicates that Bennu’s parent asteroid developed or accumulated material from a reservoir in the outer solar system ...

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