RNA contains uracil and DNA Thymine. RNA has five bases, but DNA only four. DNA contains a deoxyribose sugar, but RNA contains ribose sugar. DNA is a double strand of nucleotides, but RNA a single strand.
Uracil [edit]. Uracil is among the five nucleobases: adenine, guanine, cytosine, and thymine ,but is only found in RNA. It is a naturally occurring pyrimidine derivative with the molecular formula C 4 H 4 N 2 O 2. Uracil is planar and unsaturated and has the ability to absorb light.
