Comparing nucleotides of DNA and RNA.

0 base ll (guanine) / H H 8 phosphate groups \NHZ woo—5w A DNA nucleotide: sugar . (deoxyribose) guanine (G). or deoxyguanosine triphosphate A Guanine. one of the four nucleotides in DNA.The others (adenine. uracil. and cytosine) differ only in their component bases (blue). Three of the four bases in RNA nucleotides are identical to the bases in DNA nucleotides. base || (guanine) H 8 phosphate groups sugar An RNA nucleotide: (ribose) guanine (G). or guanosine triphosphate B Compare the RNA nucleotide guanine. The only difference between the DNA and RNA versions of guanine (or adenine, or cytosine) is that RNA has a hydroxyl group at the 2’ carbon of the sugar (shown in red).
