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?

The more researchers examine RNA, the more surprises they continue to uncover. What have we learned about RNA structure and function so far? Although RNA is a single-stranded molecule, researchers ...

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins. In reality, there is much more to the RNA story. However, in ...

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases.

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries the information contained within DNA to the ribosomes, where the genetic information is synthesized into ...

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 ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...
