Nucleic acids are macromolecules, which means they are molecules composed of many smaller molecular units. Thes units are called nucleotides, and they are chemically linked to one another in a chain.

Macromolecules - proteins, nucleic acids, and polysaccharides - are formed by the polymerization of hundreds of their low-molecular-weight precursors - amino acids, nucleotides, and simple sugars.

Sugar: In DNA, the sugar is deoxyribose, while in RNA, it is ribose.The sugar forms the backbone of the nucleic acid strand. Phosphate Group: The phosphate group is attached to the sugar and helps ...
