The antiparallel relationship of the two strands of DNA refers to the
A) twisted configuration of the strands.
B) alternative branching pattern of the strands.
C) alignment of the strands, such that one strand starts with a 3´ carbon and the other starts with a 5´ carbon.
D) view at one end of the molecule-one strand has an A wherever the other has a T, and one has a G wherever the other has a C.
E) All of the above

Question

Quizplus · Accepted Answer

The antiparallel relationship of the two strands of DNA refers to the alignment of the strands, such that one strand starts with a 3´ carbon and the other starts with a 5´ carbon. This creates an opposing polarity between the two strands that is essential for the formation of hydrogen bonds between complementary base pairs. The other options listed (A, B, D, E) do not accurately describe the antiparallel relationship of DNA strands.
