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.
