Check the mRNA and amino acid sequence in Figure 10.7. Which of the following mRNAs represents an alternative mRNA sequence that will not change the amino acid sequence? See Section 10.3 Using the genetic code to predict an amino acid sequence Your turn-a chance to practice using the genetic code

Solution

The second option is the most appropriate choice.

The first option contains T, which is absent in mRNA; this is not an mRNA sequence!

The second mRNA codes: Start-Ala-Asn-Asp-Phe-Gln-Stop

The third mRNA codes: Start-Ala-Lys-Glu-Leu-His-Stop

The fourth mRNA codes: Start-Arg-Leu-Leu-Lys-Val-Stop
