Proteins Like nucleic acids, proteins are polymers. While with nucleic acids the repeating unit is the nucleotide, with proteins, the analogous repeating unit is the amino acid. Amino acids consist of a central carbon that carries an amino group, a carboxyl group, hydrogen, and a side-chain group. Amino acids are distinguished by the properties of…

Nucleic Acids Like many biological molecules nucleic acids are polymers, long molecules formed of repeating units. With nucleic acids, the repeating unit is the nucleotide. A nucleotide consists of a five carbon sugar, a nitrogen containing base and a phosphate group. The two primary kinds of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA),…
