Solution

The correct option is A Polymers of nucleotides
DNA and RNA are chain of polynucleotide which are joined by the phosphodiester bonds. DNA resembles RNA as both has polynucleotide chain. The two nucleotide is linked by phosphodiester bond. It is formed by the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another. Two hydroxyl (OH) groups on the phosphate molecule bind to the 3’ and 5’ carbons on two independent pentose sugars to form a bond.
So, the correct answer is option A.

Q. DNA and RNA show similarity in having

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.

Which of the following sets of bases is present in both DNA and RNA?

Q. Match the following, considering nucleic acids:
