Question

Hello, I am a bit struggling with Genetics.

I have a problem:

The DNA The base composition of one stranded of a circular DNA molecule is 28% A, 20% T and 22% C.
a) What is the percentage of G in the same strand? MY ANSWER: G 30% (because 100-28-20-22=30%
b) What is the base composition of the complementary strand?MY ANSWER: (A=20%, T=28%, C=30%, G=22%
c)What is the overall base composition of the double-helical DNA? I really don't understand what they mean by 'overall base composition', do I need to divide the percentage of bases in both strands by two and give the answer?

Answer 1

(sorry, it wasn't enough space to write how I understood it):

FOR EXAMPLE: overall base composition of G: (22+30):2=26% and the same with other bases?

Answer 2

@Abhisar maybe you could have a look?:)
