A nucleic acid sequence is read from the ________ to the ________.
A)free 3' phosphate; free 5' hydroxyl
B)free 5' phosphate; free 3' hydroxyl
C)free 3' hydroxyl; free 5' phosphate
D)free 5' hydroxyl; free 3' phosphate

Question

Quizplus · Accepted Answer

A nucleic acid sequence is always read from the 5' end to the 3' end. Therefore, the free phosphate group is at the 5' end, and the free hydroxyl group is at the 3' end. Thus, the correct sequence in terms of phosphate and hydroxyl groups is free 5' phosphate to free 3' hydroxyl.
