Question

1. Nucleic Acids (DNA & RNA) are called as Deoxyribose nucleic acid and Ribose nucleic acid. Why these are called as acids ?

Solution

Nucleic acids are acidic in nature because of the presence of phosphate groups. Phosphate groups are present at the exposed surface. These phosphate groups are proton donors at neutral pH and are acidic in nature. The hydrophobic base are kept in the centre of the helix, protected from water. These bases thus, do not take part in reactions and thus make the overall chemical nature of the DNA molecule to be acidic. Same is the case for RNA.

Q. Polynucleotides are called nucleic acids. Each nucleotide is made up of three parts, i.e, a pentose sugar, a heterocyclic nitrogenous base and phosphoric acid. Depending upon the nature of sugar whether, ribose or deoxyribose, nucleic acids are called RNA and DNA respectively. In all, there are five nitrogenous bases, two of which are purines while the remaining three are pyrimidines. Out of these five bases, each type of nucleic acid has four of them.
