Questions and Answers

What is the primary function of a multiple cloning site in a plasmid?

  • To provide recognition sites for several restriction enzymes (correct)
  • To increase the copy number of the plasmid
  • To mediate DNA transfer through conjugation
  • To allow for the selection of transformed colonies

What is the purpose of a unique restriction enzyme cleavage site in a plasmid?

  • To mediate DNA transfer through conjugation
  • To provide a site for DNA sequencing
  • To confer antibiotic resistance to the host cell
  • To allow for the splicing of DNA sequences into the plasmid (correct)

What is the function of restriction enzymes in plasmid cloning?
