During replication, a double-stranded DNA molecule opens up exposing the bases on each strand. Complementary bases line up with the bases on each of the exposed original strands, forming two new strands. The sequence of bases on one of the original strands is CGGTAGGG. What is the sequence of bases on its complementary strand of DNA? (SC.912.L.16.3) *

Answer 1

The sequence of bases on the complementary strand of DNA is determined by the base pairing rules, where cytosine (C) pairs with guanine (G), and adenine (A) pairs with thymine (T). In your case, the original strand sequence is CGGTAGGG.

Using the base pairing rules, we can determine the complementary strand:

• C pairs with G
• G pairs with C
• G pairs with C
• T pairs with A
• A pairs with T
• G pairs with C
• G pairs with C

So the complementary strand for the sequence CGGTAGGG is GCCATCCC.

Thus, the answer is GCCATCCC.
