Question

Given the template strand DNA sequence 5'-TCA AAA TGG ATT CAT-3', what is the corresponding mRNA sequence (written 5'-3')?
a. ATG AAT CCA TTT TGA
b. TCA AAA TGG ATT CAT
c. AUG AAU CCA UUU UGA
d. UCA AAA UGG AUU CAU

Answer 1

Answer:

The correct answer is C) AUG AAU CCA UUU UGA.

Explanation:

First important thing to notice is that RNA doesn't have Thymine, all thymines are changed for Uracils. Then, the correspondency is thymine-Adenine, Guanine-Cytosine (and viceversa) Adenine-Uracil. Lastly, the transcription process happens from 3' to 5', so the question asks for the final result to be read to the opposite direction. Therefore, the correct answer is C.
