Select the incorrect statement for the given figure.

Options

  1. AA nucleotide has three components – a nitrogenous base, a pentose sugar (ribose in case of RNA, and deoxyribos
  2. BThere are two types of nitrogenous bases – Purines (Adenine and Guanine), and Pyrimidines (Cytosine, Uracil an
  3. CCytosine is common for both DNA and RNA and Thymine is present in RNA.
  4. DUracil is present in RNA at the place of Thymine.

Correct answer

C. Cytosine is common for both DNA and RNA and Thymine is present in RNA.

Step-by-step solution

A nucleotide has three components – a nitrogenous base, a pentose sugar (ribose in case of RNA, and deoxyribose for DNA), and a phosphate group. There are two types of nitrogenous bases – Purines (Adenine and Guanine), and Pyrimidines (Cytosine, Uracil and Thymine). Cytosine is common for both DNA and RNA and Thymine is present in DNA. Uracil is present in RNA at the place of Thymine
