Question

DNA and RNA differ in all BUT one of the following ways.
A) DNA is double-stranded, while RNA is single stranded.
B) RNA uses the sugar ribose in its backbone, while DNA uses deoxyribose.
C) DNA contains the base uracil, while RNA contains the base thymine instead.
D) DNA is found in chromosomes in the nucleus, while RNA can move around the cell.

Answer 1

A) is correct.

DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
