Question

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

Explanation:

In nucleic acid base pairing, DNA uses thymine (T) while RNA uses uracil (U). When DNA and RNA interact, adenine (A) in DNA pairs with uracil (U) in RNA, guanine (G) pairs with cytosine (C), and thymine (T) in DNA pairs with adenine (A) in RNA. Among the options, only U-A fits the valid cross-pairing between DNA and RNA.

Answer:

O U-A
