Questions and Answers

What is the purpose of the Lac Z gene in the blue-white screening method?

  • To produce the beta galactosidase enzyme for converting X-Gal into a blue compound (correct)
  • To prevent the growth of bacterial colonies
  • To allow the growth of bacterial colonies
  • To disrupt the formation of the X-Gal compound
  • Why are plasmids used in gene cloning?

  • They contain defined copy numbers that are highly regulated within a cell (correct)
  • They disrupt the formation of beta galactosidase enzyme
  • They contain a gene for producing X-Gal compound
  • They prevent the growth of bacterial colonies
  • What is the role of the antibiotic resistance gene in plasmids?

  • It disrupts the production of beta galactosidase enzyme
  • It allows cells containing the plasmid to grow in the presence of the antibiotic within the growth medium (correct)
  • It inhibits the ligation process
  • It prevents the transformation of recombinant DNA into bacterial cells
