Assume that two strands of DNA have been separated and that the base sequence on one strand is ATGC.State the sequence of bases on the second strand.
A) GCAT
B) ACTC
C) TGGC
D) TACG

Question

Quizplus · Accepted Answer

The base sequence on the second strand will be complementary to the first strand, following the base-pairing rule of A with T and C with G. Therefore, the sequence of bases on the second strand would be TAGC, which is not listed as an option. However, the options can be rearranged to find the complementary strand, and only option D) TACG results in the correct base-pairing between the two strands.
