Learning goals • Describe the characteristics of plasmids • Explain how plasmids are used in cloning a gene • Describe the function of restriction enzymes • Explain how to use restriction enzymes to create a recombinant plasmid
Key Ideas • Plasmids - ideal vectors for genetic engineering • replicate in the bacteria cell • gene promoter • antibiotic resistance as a selectable marker, • can be transferred into bacteria by conjugation. • Restriction enzymes – key to the creation of a recombinant plasmid. • cut DNA at specific sequences • sticky ends allow strands to join
What’s new? • New pARA-R plasmid
What’s new? 1. Cut the plasmid and the human DNA with the appropriate restriction enzyme 2. Insert the insulin gene into the plasmid DNA 3. Determine which antibiotic you would use to identify bacteria that have taken in the plasmid • Clone That Gene activity
Tips • Reagents should be stored in a freezer until you are ready to prepare them for students. Allow to defrost for 15 minutes before using. • The reagents can be aliquoted up to several days before the lab, then store in the freezer/refrigerator • Vortex and spin enzyme mix and 2.5x RB before aliquoting • Show the video – bio11_vid_smallvolume_450 • Show video – bio11_vid_genengdna video
Tips Multiple pans allow tubes from different classes to stay separated Low-tech water bath Calibrate and mark the controller Bottom of tubes in the water “Floatie” marked with team number. Each period has a different color. “Smart and Final” and “Thrift Store” are super resources!
