The macromolecule you are referring to is nucleic acids. Nucleic acids are polymers made up of monomers called nucleotides. There are two primary types of nucleic acids:
-
Deoxyribonucleic acid (DNA): DNA stores and transmits genetic information. It has a double-helix structure and consists of four nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
-
Ribonucleic acid (RNA): RNA plays several roles in the expression of genes and has various forms, such as messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). RNA is usually single-stranded and contains the nucleotide bases adenine (A), uracil (U), cytosine (C), and guanine (G).
Both DNA and RNA are essential for the storage, transmission, and expression of genetic information in living organisms.
