Question

which nucleotide base pairing would occur between molecules of dna and rna?
g - t
a - g
t - u
u - a

Explanation:

DNA has bases adenine (A), thymine (T), cytosine (C), and guanine (G). RNA has bases adenine (A), uracil (U), cytosine (C), and guanine (G). When DNA and RNA pair, adenine (A) in DNA pairs with uracil (U) in RNA.

U - A
