Question

You have sequenced the coding strand of a gene. The polypeptide sequence is Met-Ala-Glu-Val-Glu-Arg. What type of mutations would the following represent? G C T A a.) A substitution mutation changes the third position of codon 5 to A. b.) A deletion mutation eliminates the first position of codon 5. c.) An insertion mutation adds an A between codons 3 and 4. d.) A substitution mutation changes the second position of codon 2 to A.

Step 1

This results in the codon changing from GAG (coding for Glu) to GAA (coding for Glu). Since both codons still code for the same amino acid (Glutamine), this is a synonymous mutation. ** Show more…
