Working on the Amazon River, a biologist isolated DNA from two unknown organisms, P and Q. He discovered that the adenine content of P was 15% and the cytosine content of Q was 42%. This means that:
a) the amount of guanine in P is 15%
b) the amount of guanine and cytosine combined in P is 70%
c) the amount of adenine in Q is 42%
d)the amount of thymine in Q is 21%
e) it takes more enerfy to unwind the DNA of P than the DNA of Q
I think the answer is b, am i correct?
