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 structure of a nucleotide, consisting of a phosphate group (left), a pentose sugar molecule (middle), and a nitrogenous base (right). (Image: Public Domain) Ribonucleotides are the building blocks ...

First, he noted that the nucleotide composition of DNA varies ... that A bound to T and C bound to G within the molecular structure of DNA (Figure 2). Chargaff's realization that A = T and C ...

A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide. Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to ...

They were hardly modest, these two brash young scientists who in 1953 declared to patrons of the Eagle Pub in Cambridge, England, that they had "found the secret of life." But James Watson and ...

In 1953, Francis Crick and James Watson first described the molecular structure of DNA ... Two types of base pairing occur: nucleotide A pairs with T, and nucleotide C pairs with G.
