The decoding of information in a cell's DNA into proteins begins with a complex interaction of nucleic acids. Learn how this step inside the nucleus leads to protein synthesis in the cytoplasm.

Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure ... to thymine (T), which is the nucleobase that takes its place in DNA. Both uracil and thymine pair with ...

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

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 ...

Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's ...

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

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

(Where DNA uses thymine, RNA uses uracil.) Two nucleotides together form a base pair; the sugars and phosphates form a ...

All five nucleobases that make up DNA and RNA have now been detected in meteorite ... identified in samples from some of the same meteorites—but also cytosine, uracil, and thymine, supporting the idea ...

The building blocks for life, including salts, organic matter and amino acids have been found in samples returned to Earth ...

During the process of transcription, DNA is converted to RNA, a complex molecule that is able to carry genetic information outside of the cell's nucleus. This page guides you through the ...

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