The correct option is B False
RNA is the nucleic acid which is made up of ribose sugar, phosphate molecules and four types of nitrogenous bases which are adenine, guanine, cytosine and uracil. The nucleotide which is the smallest unit in the RNA molecule is formed by the combination of a ribose sugar, phosphate molecule and one of the nitrogenous bases.

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.
