Match the following strand of DNA with its complementary strand: C T T G A A C T G T A
Annette [7]

Answer: C

Explanation:

Hi, the answer to this problem is C.

This is because it is asking for the complementary strand.

Basically, the nucleotide A goes with T, and C goes with G, and both vise versa.

Since this is DNA, A goes with T.

So you would match it up. For the first one, we have C. That means for the first letter of the correct answer, it should be G. Do this until you get through the whole sequence, and eventually, you will get the answer C.

Hope this helps!
