pentose

A sugar with five carbon atoms in each molecule. The ‘backbone’ of DNA on each side of the helix consists of a chain of pentose sugars alternating with phosphate groups. The sugar in DNA is 2-deoxyribose, and in RNA is ribose. The NUCLEOTIDE chain is formed by linking the 5’ position of one pentose ring to the 3’ position on the next via a phosphate group. 5’ and 3’ are used to indicate the ends of a DNA fragment and the directions in which the ‘backbones’ run.
