An operon which encodes enzymes that are involved in the biosynthesis of an amino acid in prokaryotes, begins with a sequence coding for a leader peptide that has no known enzymatic function

Based on the following DNA sequence corresponding to the leader peptide region, determine its sequence using the following table. 5-AAUUUUUAUGACACGCGUUCAAUUUAAACA CCACCAUCAUCACCAUCACCCUGAC-3

and what is the amino acid this operon is responsible to synthesize? Explain how the expression of this operon is regulated by taking advantage of this leader peptide
