i'm not sure what i think cause i don't know this . lol . but thank you (:

Answer 4

dark0nebeauty is right. It's B.

There are just two things that we need to remember here:

1. A pairs with T
2. G pairs with C

So, let's look at both the sequence in the problem (top),
and the complimentary sequence (bottom).

TACG
ATGC

You see how A and T go together...
And G and C go together?

That's how it works.

Answer 5

ATGC
