Because of the base pairing in DNA, the amount of
A is about equal to the amount of G
T is about equal to the amount of A
A is greater than the amount of T
C is much greater than the amount of G
Which is the matching DNA strand during replication for this DNA sequence: A-T-C-G-A-T
U-A-G-C-U-A
T-A-G-C-T-A
T-A-C-G-T-A
T-A-G-C-A-T
