Biology 1 Question?

Considering the two sugars that can form nucleotides (ribose and deoxyribose) and the 5 nitrogenous bases (A, U, C, G, T) that can be attached to the sugars, how many total different nucleotides of RNA and DNA actually exist in normal cells?

    RNA always has ribose sugar and either U,A ,G or C as a base

    So there are 4 different options for RNA

    DNA always has deoxyribose sugar and either A T G or C

    So also has 4 possible options

    4+4 = 8

    So I would say 8 different nucleotides
