Dr. S is оbsessed with the mоvie Jurаssic Pаrk аnd has decided that she wоuld like to clone a cryolophosaurus (AKA Elvisaurus because it has a furrowed brow that looks like a pompadour). To do this, she sneeks into the archives of the Museum of Natural History and swabs a bone that she believes belonged (at one time) to a cryolophosaurus, hoping that it has some ancient dinosaur DNA. Dr. S amplified the DNA using PCR and performed restriction digests to determine which sites are present on the DNA (see map below). a. Dr. S has only a limited amount of DNA and would like more. She would like to clone in the largest possible fragment of dinosaur DNA into a plasmid vector (pUC19) and she would like to use the same enzyme to cut both vector and dino DNA and so she decides to cut with EcoRI. After she cuts the DNA, she mixes vector and dino DNA in a microcentrifuge tube and adds an enzyme to connect the DNA fragments to each other in hopes of generating a recombinant DNA molecule. What enzyme did she use to link the molecules together? b. Next, Dr. S transforms the DNA into the bacterial cells and selects for cells that have taken up a plasmid. In a few words describe how Dr. S selects for cells that have taken up a plasmid. c. A chemical called X-gal is added to the plates the transformed bacteria are grown on and is used to determine which colonies have cells that have taken up a recombinant plasmid vs. cells that have take up a vector without an insert. What color are the colonies that have taken up a recombinant plasmid (vector+insert)? d. BamHI is a restriction enzyme that has a recognition sequence that is 6 base pairs long. Based on the size of the recognition sequence it should cut once every base pairs.
