1. A gene coding for a protein has two alleles.

Figure 1 shows the first 5 codons of an mRNA strand for these alleles.

Allele 1 – AUG CCA CAG GAG UUC

Allele 2 – AUG CCA GAG GAG UUC

Figure 1

Allele 2 has a mutation.

Figure 2 shows the key needed to predict the translated amino acid sequence of the protein.

Figure 2

Explain how the mutation in allele 2 could affect the functioning of this protein.
