Please see the image. The mutation causes no alteration in the protein since both the normal and the mutated codons code for leucine.
Work Step by Step
This is a silent substitution-- both codons code for leu. The complementary sequence is found by using the A-T and G-C base pairing rules, and the mRNA is the same as the non-coding strand with T replaced by U. Use p. 339 to find the amino acids.
