You are studying a new operon in bacteria involved in tyrosine biosynthesis.
(a) You sequence the operon and discover that it contains a short open reading frame at the 5′ end of the operon that contains two codons for tyrosine. What prediction would you make about this leader sequence, the RNA transcript, and the peptide that it encodes?
(b) How would you predict this operon is regulated; i.e., is it inducible or repressible by tyrosine? Why?
(c) Would this kind of regulation work in a eukaryotic cell? Why or why not?
