Which structure shows the 3 residue segment of DNA with the following sequence: (3' end) GAT (5' end) ?
A) 
B) 
C) 
D) 
Residue Segment
A portion of a macromolecule, particularly in biopolymers, consisting of a sequence of monomers covalently bonded together.
DNA Sequence

Final Answer :
B
Explanation :
In the given sequence, the 3' end has the nucleotide G (guanine), followed by A (adenine) and T (thymine) and then the 5' end. This means that the complementary strand would have C (cytosine), T (thymine) and A (adenine) in the same order.
Looking at the given options, only option B has the required fragment with the sequence GAT, which would have the complementary strand CAT. The other options do not have the required fragment or have different nucleotides in the given segment.
