#1) A DNA strand has the sequence GTTCCAGAG. Which is the complementary strand of RNA?

In order for us to get the complementary strand of DNA to the sequence presented above we will simply have to remember that A pairs with T and G pairs with C. We now simply go through it replacing the letters using this rule. We will get the Following: CAAGGTCTC. But for this case it is different. We have to find from DNA to RNA, therefore we will use the rule of A pairs with U and T pairs with A. We get the following: CAAGGUCUC. The correct choice is C).

I hope it helps, Regards.

Where are they though?
