A certain genetic condition in horses is caused by a single base mutation in a gene. Part of the gene sequence containing the mutation is shown. a. Determine the mRNA sequence.

b. Determine the amino acid sequence that is coded for by the mRNA sequence you determined in part (a)

The mutated gene codes for Leu instead of Phe.

c. Identify a single base change in the DNA sequence shown that would cause this genetic condition in horses. Explain your answer using amino acids, mRNA codons, and DNA triplets.
