What is DNA?

DNA is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.


Ribonucleic acid (RNA) is a polymeric molecule. It is implicated in a varied sort of biological roles in coding, decoding, regulation, and expression of genes.The three types of RNA are:
mRNA (messenger RNA) - carries genetic information from the nucleus to the cytoplasm
tRNA (transfer RNA) - brings amino acids to ribosomes during protein synthesis
rRNA (ribosomal RNA) - guides the translation of mRNA into a protein.
