Questions and Answers

What is the purpose of using restriction endonucleases in the production of recombinant DNA?

  • To increase the pore sizes of the plasma membranes
  • To identify the specific DNA fragment of interest
  • To cleave the source DNA and plasmid or viral vectors at the same sites (correct)
  • To join the DNA fragments to the plasmid or viral vector
  • What is the purpose of the 'heat shock' step in the plasmid insertion by heat shock treatment method?

  • To concentrate the plasmids near the cells
  • To increase the pore sizes of the plasma membranes
  • To select for cells that have taken up the plasmid
  • To allow the plasmid DNA to enter the cells (correct)
  • What is the purpose of including an antibiotic resistance gene in the plasmid DNA sequence?

  • To allow only 'transformed' cells to survive in the presence of the antibiotic (correct)
  • To increase the pore sizes of the plasma membranes
  • To concentrate the plasmids near the cells
  • To select for cells that have taken up the plasmid
  • What is the purpose of the 'hybridization' step in the screening of recombinant cells?
