DNA and RNA are called nucleic acids because they contain phosphate groups that give them an acidic nature. Nucleic acids store and transmit genetic information by controlling protein synthesis in cells. They also direct RNA synthesis, store chemical energy as molecules like ATP, act as co-enzymes, and serve as secondary messengers in signal transduction pathways.

Why are dna and rna called acids AND FUNCTIONS OF NUCLEIC ACIDS
- 1. Why are DNA and RNA called acids? • DNA or RNA are called nucleic acids because of the acidic nature of the phosphate group attached to them. • The phosphodiester bond can easily lose the proton in the presence of nucleophile group subsequently masking the basic nature of nitrogenous bases.
- 3. Functions of Nucleic acids • Transmission of Hereditary Characters • Store house of Genetic information and control protein synthesis in cell. • Direct synthesis of RNA • Storage of chemical energy, eg: AMP, ADP, ATP • Form part of co-enzymes, eg: NAD+, NADP+, FAD and Co-enzyme A. • Act as secondary messengers in signal transduction, eg: cAMP
