Uracil is often compared to thymine (T), which is the nucleobase that takes its place in DNA. Both uracil and thymine pair with adenine, but they differ in their chemical structure. Thymine has an ...

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

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.

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

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

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

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

Analyzing a sample from an asteroid named Bennu reveals the chemicals necessary to form DNA and RNA.

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

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

Importantly they also discovered all five nitrogenous bases — adenine, guanine, cytosine, thymine, and uracil — that are necessary to build DNA and RNA. Finally they found traces of important ...
