If a DNA strand contains 12% thymine, it also contains ____

a. 12% A, 38% G, 38% C
b. 12% A, 12% G, 38% C
c. 12% A, 12% G, 12% C
d. 38% A, 12% G, 38% C

Answer:

If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.  

Explanation:
A=T
so A is 12% too
100-(12+12)
=100-24
=76
then divide by 2 to get each C and G
76/2=38
so C and G are each 38%

the answer is option A

hope this helps !
