What are the three main functions of DNA?

The three main functions of DNA are as follows.
  • To form proteins and RNA.
  • To exchange the genetic material of parental chromosomes during meiotic cell division.
  • To facilitate occurring mutations and even mutational change in a single nucleotide pair, called point mutation.

Correspondingly, what is DNA and explain its function?

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

How does DNA dictate the functions of a cell?

(Marieb 52) DNA is able to dictate the functions of a particular cell by providing instructions and holding the code for proteins. Then, this information is kept by the messenger molecule and translated into a comprehensible language of amino acids, the building blocks of proteins, that can be understood.

What does DNA control in the body?

The nucleus of a cell contains chromosomes, which carry genetic information in a long molecule called DNA. Genes are regions of DNA that carry the code to control a particular cell activity or the production of a particular protein.
