operon is the coordinate unit of genetic expression in bacteria.
Tryptophan is amino acid that is required for the growth and development. So when it is needed to bacteria it is synthesized by the coordination expression of genes that is present in the bacterial chromosome.
Topics covered in this video is
Overview
Structure of trp operon
Regulation of trp operon
Attenuation of trp operon
Structure of trp operon contains promoter, operator, structural genes.
Promoter is the site where RNA Polymerase is bind.
Operator is the site where repressor protein is bind.
Five structural genes that encodes enzymes for biosynthesis of tryptophan.
