ADNA strand has the sequence GTTCCAGAG. Which is the complementary strand of RNA? O CAAGGTCTC
O AGGTTCACA
4
O CAAGGUCUC
OTGGAACTCA

CAAGGUCUC

Explanation:

To solve this question, we must know the base-paring rules of DNA and RNA.

Here is the following rule for a strand of DNA:

Adenine bonds with thymine  

Cytosine bonds with guanine

Now, here is the following rule for a strand of RNA:

Uracil bonds with Adenine

Cytosine bonds with guanine

By the way, the attachments that I provided are resources from my teacher on this topic!

So now that we know the following rules, we can use these rules to find the complementary strand of RNA, and to do this, all we need to do is simply use the base-pairing rules to find the complementary nitrogenous base (adenine, guanine, cytosine, uracil) for RNA.

In conclusion, the complementary strand of RNA for the DNA molecule is CAAGGUCUC.

A) CAAGGTCT

Explanation:

The answer is A because A = T and C = G in the case of DNA matching. It's not CAAGGUCUG because Uracil is not part of the DNA sequence matching.
