Question

The base pairs of DNA are correctly shown as?

• A. A $\equiv$ T and C = G
• B. A = T and C = G
• C. A = T and C $\equiv$ G
• D. A $\equiv$ T and C $\equiv$ G

Answer 1

Answer: (C)

A = T and C $\equiv$ G

• In DNA, purines pair with pyrimidines. Adenine pairs with Thymine using two Hydrogen bonds.
• Guanine pairs with Cytosine with the help of three Hydrogen bond.

So, the correct answer is 'A = T and C≡ G'.

G'
