what is DNA? explain its functions.

DNA stands for deoxyribonucleic acid. DNA consists of long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a deoxyribose sugar and a phosphate group. It is a genetic material that containing the genetic instructions used in the development and functioning of all known living organisms.

Function of DNA:

  • DNA is the genetic material that can influence the phenotype of all living organisms. It carries the genetic instructions of an organism’s birth, development, reproduction and even death.
  • DNA helps to inherit by transferring genetic information to daughter cells from parent cells while cell division.
  • DNA contains the code for protein synthesis.
  • DNA replicates to help in reproduction, growth and development.
