Explanation:

Nucleic acids (DNA and RNA) are polymers made up of nucleotides, which consist of a sugar, a phosphate group, and a nitrogen - containing base. In the process of translation shown in the second figure, the molecule being read by the ribosome to make a peptide chain is mRNA. mRNA is a type of nucleic acid involved in protein synthesis.
