Answer:
A and F are phosphate groups.
B and E are sugars.
C and D are nitrogenous bases.
Explanation:
Nucleotides are the molecules responsible for composing DNA and RNA. They are formed by three units: a phosphate group, a sugar molecule and a nitrogenous base.
The sugar molecule is a pentose, which means that it is a molecule formed by 5 carbons. These collections are represented by geometrical figures such as the letters "B" and "E" shown in the figure above, where each tip represents a carbon.
The nitrogenous bases are molecules that are named adenine (A) and guanine (G) and the pyrimidine bases cytosine (C), uracil (U) and thymine (T).
The phosphate group, in turn, is a molecule derived from phosphoric acid and is the only one that does not vary in each nucleotide.
The answer is nucleotides
