Beta-Galactosidase and Western Blot 0 1. EMG 9 and EMG 26 contain strain _lac-_(I- Z+ Y+) and strain _lac -_ (I+ Z- Y-)respectively.Three genes huddled together on the chromosome are required for two strains of _E.coli_ to utilize lactose.Consisting of three genes‚ namely‚ _lacZ_‚ _lacY_ and _lacA_‚ the _lac_ operon orderly handles these genes to code specific enzymes necessary for the metabolism of lactose. The genes _lacZ_‚ _lacY_ and _lacI_ would code for beta-galactosidase‚ galactosidase permease
