Here's why:
* Nucleotides are the building blocks of nucleic acids. They consist of a sugar (deoxyribose or ribose), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil).
* Nucleic acids are long polymers of nucleotides linked together by phosphodiester bonds.
* There are two main types of nucleic acids:
* Deoxyribonucleic acid (DNA) stores genetic information and is found in the nucleus of cells.
* Ribonucleic acid (RNA) plays a role in protein synthesis and is found in the cytoplasm of cells.
So, to summarize, a nucleic acid is a molecule composed of many nucleotides linked together.
