DO NOT PUT A LINK What is the complementary strand for the following DNA sequence: A - T - C - T - G - T - A

T-A-G-A-C-A-T

T  A  C  A  G  A  T

Explanation:

A becomes T, and T becomes A

C becomes G, and G becomes C on the complementary strand.

If I remember correctly, you reverse the order as well

So we have                    A  T  C  T  G  T  A

Pairing it up gives us     T  A  G  A  C  A  T

but we have to reverse that order, giving us:

T  A  C  A  G  A  T

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
