The percentage of nucleotide A in DNA isolated from human liver is observed to be 29.6%. What is the expected percentage of T, G and C? Justify.

Text Solution

Verified by Experts

a. T = 30.7%, G = 19.3%, C= 19.3%
b. The amount of A is always equal to T. So the percentage of T is expected to be very close to 30.7%. G and C together would make up the remainder or 100 - (30.7 + 30.7) = 38.6. Thus the percentage of C and G separately would be expected to be equal or half of 38. 6 or 19.3
