Nucleic acid

Nucleic acids are a type of biological molecule that play a critical role in the storage, transmission, and expression of genetic information. They are composed of building blocks called nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base.

About

They are composed of building blocks called nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. There are two main types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA carries the genetic instructions for the development and functioning of all living organisms, while RNA is involved in various biological processes, including protein synthesis. The structure of nucleic acids allows them to store and transmit genetic information by means of the specific pairing of complementary nitrogenous bases (adenine with thymine in DNA, and adenine with uracil in RNA, as well as guanine with cytosine). Additionally, nucleic acids are involved in a wide range of other cellular processes, such as gene regulation and cell signaling.
