Answer: The complementary strand of the DNA is T A A G C T A G C T G C
Explanation: The semi-conservative replication means that each strand of the double stranded DNA serves as a template for the synthesis of a new strand and that the two DNA molecules synthesized during replication each contains one parent strand and one new strand that is complementary to the parent strand.
In DNA base pairing, thymine pairs with adenine while guanine pairs with cytosine: G=C and T=A.
