Using Figure 17.6, identify a 5′→3′ sequence of nucleotides in the DNA template strand for an mRNA coding for the polypeptide sequence Phe-Pro-Lys. a. 5′-UUUCCCAAA-3′ b. 5′-GAACCCCTT-3′ c. 5′-CTTCGGGAA-3′ d. 5′-AAACCCUUU-3′

Hi everyone here, we have a question telling us the sequence of an M r n A is five prime. U G G U c c A c G G c U three prime, identify the correct sequence of nucleotides in the DNA template strand from which this M RNA is synthesized. So let's rewrite this. Our first step is going to be to start at three prime instead of five prime. And then we need to remember our rules. A is going to bind to U N G is going to bind to C. So we're going to have a C c A G G and we're going to have a tea because this is DNA not M R N A. So A is going to bind to T g c c g A And it will end up five prime. So our answer here is D three prime A C c a G g t g c c g a five prime. Thank you for watching. Bye.
