Looking at the DNA sequence provided (5’ATGGTCAGT3’), we can tell what the complementary DNA sequence will be. This question is testing your knowledge on complementary base pairing in strands of DNA. Complementary base pairing in DNA is when guanine forms three hydrogen bonds with cytosine and adenine forms three hydrogen bonds with thymine.
This rule states that adenine can ONLY bind to thymine, and guanine can ONLY bind to guanine. Therefore, adenine on one strand will be complementary to thymine on the second strand, and the same goes for cytosine and guanine. If one strand is positioned in 5’ to 3’ direction, the other strand is positioned in 3’ to 5’ direction. Therefore, options A, B, and D are incorrect.
