Solution
both (b) and (c)
If 30% of an organism’s DNA is thymine, then 30% is adenine and 70% is guanine.
Explanation:
Adenine = Thymine, since Thymine is 30%, Adenine must also be 30%. Guanine = Cytosine. The total DNA is 100%. If A + T is 60% (30 + 30), the remaining 40% is shared equally by G and C.
