Question

If Adenine always pairs with Thymine and Guanine always pairs with Cytosine, what % of

DNA would be made up of Cytosine if 20% was made up of Adenine?
A. 20 B.30 C.40 D.60

Answer 1

option b is correct

Step-by-step explanation:

if adenine is 20% so thymine is also 20% because equal amount thymine and adenine make a base pair the remaining percentage is 60% which is contributed by cytosine and guanine so cytosine contribute 30% and cytosine also contribute 30%
