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.
1 Adenine and guanine are both found in DNA and RNA. 2  Cytosine, thymine and uracil are pyrmidines (contains a six membered ring of carbon and nitrogen).  Cytosine is found in both DNA and RNA, but thymine is only found in DNA and uracil is only found in RNA.
