Question

A chromosome has 13% G. What percentage of
A, C, and T does this DNA molecule have?

Answer 1

a 37%

c 13%

t 37%

Step-by-step explanation:

c and g go together so a must have the same as g (13%)

a and t go together so they must have equal amounts

100%-13%-13%=how much is left=74%

split this evenly between a and t

74/2=37
