Explanation:
DNA is a nucleic acid molecule that is composed of nucleotides. The nucleotide is composed of four different types of nitrogenous bases, a phosphate group, and the deoxy-ribose sugar.
The DNA molecule is used by the organism to store the information of organisms for a long time. The nitrogenous base in the DNA codes for different types of amino acids in the organism which can form proteins. The proteins can perform various roles in the organism.
