Question

Match the following DNA strand to its complementary strand of RNA

TTA - CAA - ACC - ATA

Question options:
AAU - GUU - UGG - UAU
AAT - GTT - TGG - TAT
AAU - CTT - TGG - TAT
ATG - CCG - AAT - TCG

Answer 1

The first option: AAU - GUU - UGG - UAU

Step-by-step explanation:

RNA has the nitrogenous bases adenine (A), uracil (U), guanine (G), and cytosine (C). A pairs with U while G pairs with C. The thymine (T) from the DNA must be complemented by the adenine (A) from the RNA, too.

Knowing this, the complementary strand of RNA would be the first option. Another way of finding the answer would be noticing that all the other options have thymine (T), which is a nitrogenous base RNA does not have.

Answer 2

AAU - GUU - UGG - UAU

Step-by-step explanation:

Thymine is present in RNA strands as the base Uracil, making there an inability to have Thymine in an RNA strand.

Hope this helped :)
