About Lesson
  • The lac segment of E. coli chromosome is known to include 3 genes for enzymes production i.e. Z for beta galactosidase, Y for beta galactoside permease and A for thiogalactoside.
  • Beta galactoside permease: Responsible for transport of lactose.
  • Beta galactosidase: Responsible for hydrolysis of lactose to galactose and glucose.
  • The 3 genes are closely linked and regulated together.
  • The genetic information of 3 genes s transcribed into a single mRNA molecule that is subsequently translated into the polypeptide chains of the 3 enzymes.
