Explain the term nucleic acid.
Nucleic acids are crucial biomolecules found in all living organisms. Because nucleotides have a repeating structure, they are also known as polynucleotides. A phosphate group, sugar, and nitrogenous bases make up nucleic acid.
Nucleic acid types include:
RNA: The structure of RNA (ribonucleic acid) is a single-stranded helix.
DNA: The double-stranded helix structure of DNA (deoxyribonucleic acid).
