What are nucleic acids ? Mention their two important functions.

Answer

Nucleic acids are biomolecules which are found in the nuclei of all living cells inform of nucleoproteins or chromosomers (proteins containing nucleic acids as the prosthetic group) Nucleic acids are of two types : deoxyribonucleic acid `(DNA)` and ribouncleic acid `(RNA)`. The two main functions of nucleic acids are :
(i) `DNA` is respondible for transmission of hereditary effects from one generation to another. This is due to the daughter cells.
(ii) `DNA` and `RNA` ar responsible for synthesis of all proteins needed for the growth an maintenance of our body. Actually the proteins are synthesized by varies `RNA` molecules (`y-RNA,m-RNA` and `t-RNA`) in the cell but the message for the synthesis of a particular protein is given by `DNA` molecules.
