Lab Four: Restriction Digest

pAMP, BamHI, EcoRI, and HindIII are the main players in this game!

What is important in this lab?
  • What do restriction enzymes do?
  • What are sticky ends? Blunt ends?
  • What are plasmids? pAMP?
  • Why do we leave some restriction enzymes out of the mixes?
  • Why do we use gel electrophoresis?

What do the enzymes do?
  • They cut at specific sequences. They make circular plasmids into linear strands of DNA!
What happens when you put in more than one enzyme?
  • You get multiple cuts which means multiple strands of DNA.
Why do we use gel electrophoresis?
  • To determine the size of the fragments after the cuts
  • To determine the plasmid map and where in relation to one another the enzymes cut.
