The colonies of recombinat bacteria appear white in contrast to blue colonies of non-recombinant bacteria
because of :
  • a)
    Non-recombinant bacteria containing betagalactosidase
  • b)
    Insertional inactivation of alphagalactosidase in non-recombinant bacteria
  • c)
    Insertional inactivation of alphagalactosidase in recombinant bacteria
  • d)
    Inactivation of glycosidase enzyme in recombinant bacteria
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The colonies of recombinat bacteria appear white in contrast to blue c...
If insertion inactivation of α-galactosidase or z-gene of lac-operon in plasmid of E.Coli take place then it will
not produce α-galactosidase or lactase enzyme (this enzyme convert x-gel chromogen into blue colour) due
to lack of this enzyme this reaction does not take place so recombinant bacteria appears white in contrast to
blue colonies.
