Do Nucleotides Have a Carboxyl Group?

Nucleic acids (i.e., DNA and RNA) are made up of nucleotide monomers. ... Each amino acid comprises a central carbon atom linked to a carboxylic acid group, a nitrogen-containing amine, a hydrogen atom, and one of twenty different side chain groups that defines the amino acid.

Do nucleic acids have carboxyl groups?

A common functional group found in amino acids is the amino group −NH2 (Figure 2). Other commonly occurring functional groups include carboxyl groups (−COOH) in amino acids, methyl groups (−CH3), and phosphate groups (–PO3) in nucleic acids.

What is a nucleotide made of?

A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
