The correct answer to the question is:
Fatty acid group
Explanation:
1. Nucleic acids are macromolecules that consist of nucleotide monomers. These nucleotides are made up of three components: a phosphate group, a pentose sugar, and a nitrogenous base.
2. The phosphate group is responsible for linking the nucleotides together in the nucleic acid chain.
3. The pentose sugar (like ribose or deoxyribose) provides the structural backbone for the nucleic acid molecule.
4. The nitrogenous base (such as adenine, thymine, cytosine, or guanine) carries genetic information and pairs with another base in DNA or RNA.
5. Fatty acids, on the other hand, are not part of nucleic acids. Fatty acids are components of lipids, not nucleic acids.
