Correct! Wrong!

Question: Which one of the following pair of nitrogenous bases of nucleic acids, is wrongly matched with the category mentioned against it? Answer: (D) Adenine, Thymine - Purines

DNA and RNA are genetic materials chemically known as nucleic acids. DNA and RNA are polymers of nucleotides. A nucleotide is made up of a nitrogenous base, a pentose sugar, and a phosphoric acid. The nitrogenous bases present in DNA are Adenine, Guanine, Thymine, and Cytosine and for RNA are Adenine, Guanine, Uracil, and Cytosine.

The nitrogenous bases are divided into two types (i) purine and (ii) pyrimidines. Purines are heterocyclic compounds with two rings. On the other hand, pyrimidines are single-ring compounds. Examples of purines are Adenine and Guanine. Examples of pyrimidines are thymine, cytosine, uracil.

Therefore (D) Adenine, Thymine – Purines is wrong.
