    Firstly, it contains a different sugar group in the sugar phosphate backbone of the molecule: ribose instead of deoxyribose. Secondly, it still uses the bases A, G and C, but instead of the base T, it uses uracil, U. The structure of uracil is very similar to thymine, with the absence of a methyl (CH 3) group being the only difference.
