multiple-choice question
what are the paring role for dna - rna
a - u
t - g
a - u
g - c
a - t
g - c

Explanation:

In DNA - RNA pairing (such as during transcription), adenine (A) in DNA pairs with uracil (U) in RNA, and guanine (G) in DNA pairs with cytosine (C) in RNA. Thymine (T) is in DNA and pairs with A in DNA - DNA, but in DNA - RNA, A pairs with U. The first option has T - G which is incorrect. The third option has A - T which is DNA - DNA pairing. So the correct pairing is A - U and G - C.

Answer:

B. A - U, G - C
