Question

dna and rna are each made up of slightly different types of nucleotides. what is the difference in nucleotides between rna and dna?
no differences exist in the nucleotide makeup of rna and dna.
dna has u and rna has t.
rna has u and dna has t.
rna has g and dna has c.

Explanation:

Nucleotides in DNA contain thymine (T), while RNA nucleotides contain uracil (U) instead of T. Other nucleotide bases (adenine, guanine, cytosine) are shared between RNA and DNA.

Answer:

RNA has U and DNA has T.
