Which of these are the correct base pairs of dna?

a. adenine and uracil

b. cytosine and guanine

c. cytosine adenine

d. thymine and guanine

Option (B) is the correct answer.

Explanation:

DNA means deoxyribonucleic acid which helps in determining the characteristics of a living thing. Base pairs present a DNA molecule are adenine, guanine, thymine and cytosine.

The complemetary base pair of adenine is thymine and vice-versa.

Whereas the complementary base pair of guanine is cytosine and vice-versa.

Thus, we can conclude that out of the given options cytosine and guanine are the correct base pairs of DNA.
