DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

DNA isn’t the only decorated nucleic acid in the cell. Modifications to RNA molecules are much more common and are critical for regulating diverse biological processes. For years, researchers ...

Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation ...

In (+)-stranded RNA viruses, RNA is the sole genetic material. Because infected host cells ordinarily lack RNA-dependent RNA polymerase (RdRp) activity, these RNA viruses encode a replicative ...

The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...
