Question

Analysis of a viral genome reveals that it is composed of a double stranded DNA molecule containing 24% T (thymine). Based on this information, what would be the percentage of cytosine

Answer 1

All the thymine(T) pairs with adenine(A) this means that we have the same number of thymine and adenine nucleotides, and the same percentage, hence we have 24% adenine

100-24-24=52%

This 52% is made of guanine and cytosine. We know that all the guanine and cytosine are paired together so we have the same numer of cytosine and guanine bases

2C=52

C=52/2

C=26% cytosine

Answer 2

Step-by-step explanation:

Remember that Adenine and Thymine nucleotides have the same number whereas Cytosine and Guanine have the same number.

Therefore there is:

24% of Adenine

100% - 24% * 2 = 52% of Cytosine + Guanine

52% / 2 = 26% of Cytosine.
