What sequence of bases would be complementary to A-G-C-T-A?

Answer 1

DNA:
T-C-G-A-T

mRNA:
U-C-G-A-U

mRNA rule: switch T with U
_________________________________________
Although the above answer is correct in that there are no thymines (T) in RNA, I must disagree with the rest of the answer. The mRNA strand given in the answer above would be the identical strand made from RNA, not the complementary strand as the question asked for.
A complementary strand is produced by an RNA or DNA polymerase from a template DNA strand.

Therefore, if the template DNA strand were T-C-G-A-T, then:

The complementary DNA strand would be A-G-C-T-A
The complementary RNA strand would be A-G-C-U-A

Answer 2

The sequence of bases complementary of the strand would be:

C C G T C A A G T A C G.

Answer 3

DNA: AGTGCAT

mRNA: AGUGCAU

Answer 4

A-G-T-T-C-G
