Quizplus · Accepted Answer

The convention for writing a nucleotide sequence is left to right, starting with the 5' end. The 5' end is the end with a phosphate group attached to the 5' carbon of the sugar molecule in the nucleotide. The 3' end is the end with a hydroxyl group attached to the 3' carbon of the sugar molecule. Therefore, the correct answer is left to right;5' end. Choice C matches this convention.
