1. How may recombinant DNA molecules be introduced into human cells? a. by splicing the needed genes into a mammalian chromosome using restriction enzymes. b. by adding plasmids to the mammalian cells. c. by using engineered viruses as vectors. d. by using a gene gun. 2. If someone is accused of a crime, investigators can collect his or her DNA to compare the DNA of the cells found at the crime scene. To collect human DNA, investigators often swab the inside of person’s cheek. Just a few human cheek cells contain enough material to perform PCR.

1. Write if the statement is true and modify the statement with the correct answer if its false a. E. coli strains used in blue-white screening produce blue color complexes because their beta-galactosidases are activated via alpha-complementation. b. If you are a researcher trying to identify a gene that is responsible for a trait of interest, the first thing that you would do is to make a review of the literature that is available. c. The polylinker region in plasmids is where specific DNA sequences are cut by non-specific restriction enzymes. d. Blue-white screening is one of the last steps involved in determining if the gene of interest has been inserted successfully in plasmids.
