The figure below is a nucleotide: 
- If this molecule were found in a DNA chain,the chemical group labeled X would be and the chemical labeled Y would be_________ .
A)OH; H 
B)OH; OH 
C)H; OH 
D)H; H

Quizplus · Accepted Answer

In a DNA chain, the chemical group labeled X on the nucleotide would be an OH group because it would be involved in forming a phosphodiester bond with the next nucleotide. The chemical group labeled Y would be an H, as it is a hydrogen atom attached to the 5' carbon of the sugar molecule in the nucleotide.
