Answer:
22% base G
Explanation:
background info
nucleotides pairs:
T-A (thymine- adenine)
C-G (cytosine- guanine)
because they are pairs, there is an equal amount of T and A. and an equal amount of C and G
# of T= # of A
# of C= # of G
-----------solve
28% is T, then 28% is A
28*2=56%
100-56= 44%
44% left for C and G
44/2=22 (because C and G amounts are equal)
22% C and 22% G
