The correct answer is this one: "C. ACCGUGAGGUC."
The sequence of an mRNA transcript is UGGCACUCCAG. In mRNA uracil (U) replaces Thymine (T) and forms a base pair with adenine (A). On the other hand, Guanine (G) and Cytosine (C) form base pairs.
In summary,
U <--> A
G <--> C
From the transcript,
UGGCACUCCAG <- mRNA
ACCGUGAGGUC <- template, your answer!
Here are the choices
A. UGGCACUCCAG
B. ACCGTGAGGTC
C. ACCGUGAGGUC
