1 answer
Nucleic acids are macromolecules that are essential for storing and processing genetic information in living organisms. They are made up of nucleotide monomers, which consist of a sugar, a phosphate group, and a nitrogenous base. The two main types of nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA carries the genetic instructions for the development, functioning, growth, and reproduction of all organisms, while RNA helps in the synthesis of proteins based on the instructions carried by DNA.
