A)AAUUGCGCUAU
B)AATTGCGCTAT
C)UUTTGCGCTUT
D)TTAACGCGATA
E)AATTUCUCTAT

Question

During transcription, DNA is used as a template to make mRNA. The base pairing rules change slightly: adenine (A) pairs with uracil (U) in RNA instead of thymine (T), and cytosine (C) still pairs with guanine (G). Therefore, the DNA sequence TTAACGCGATA corresponds to the mRNA sequence AAUUGCGCUAU.
