Nucleic acids:
“The particles in the nucleus of the cell, responsible for heredity, are called chromosomes which are made up of proteins and another type of biomolecules called nucleic acids.”
Nucleic acid is categorized into two types that are discussed below:
Deoxyribonucleic acid(DNA)
Ribonucleic acid (RNA)
DNA:
DNA has a double-stranded structure.
DNA is the chemical basis of heredity and has the coded message for proteins to be synthesized in the cell.
DNA contains four bases viz. adenine (A), guanine (G), cytosine (C), and thymine (T).
RNA:
RNA has a single-stranded structure.
RNA also contains four bases, the first three bases are the same as in DNA but the fourth one is uracil (U).
