The molecule on the right is an example of
a deoxyribonucleotide. There are three components of all nucleotides: a
pentose sugar, a phosphate group, and a nitrogenous base. In this case
the nitrogenous base is cytosine (no fill color), a 6-member
single-ring pyrimidine. The pentose sugar (blue fill) is deoxyribose.
Do you know why? The phosphate group is shown in yellow. The correct
name of this molecule is Deoxycytidylic acid. It can also be called
cytosine monophosphate
