You are studying a protein, and a small fragment of its sequence is shown below.You have decided that the glutamine in the protein segment has an important role in its function.You decide to change this glutamine to a lysine by changing only one base.Given the partial mRNA sequence that codes for this stretch of protein below, write the new sequence for this stretch of RNA if you were to make this change.Be sure to label the 5′ and 3′ ends.
