Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally. This is where DNA and RNA ...

These chains come in a wide range of lengths. In humans a typical protein is about 400 amino acids long; some are a lot longer. Molecules of RNA, one of the two nucleic acids, can reach up to 100,000 ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...

Genes contain instructions for protein production, and the central dogma of biology states that this information flows from DNA to RNA to proteins. However, only about 2% of the human genome actually ...

Scientists are exploring how RNA might have jump-started life four billion years ago and how it's now advancing drug ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

Unquestionably, we will emerge from this revolutionary period with modified views of components of cells and how they operate, but only, however, to await the emergence of the next revolutionary phase ...

Researchers have demonstrated a technology capable of a suite of data storage and computing functions -- repeatedly storing, retrieving, computing, erasing or rewriting data -- that uses DNA rather ...
