1. A genetic mutation that is seen in the parental cell line of a human cell type but not in the offspring is: A. Never seen. All genetic mutations are passed on to the progeny B. A somatic mutation C. A germ-line mutation D. Not seen in cancer cells E. Always due to a point mutation 2. Did the Griffith experiments (the ones with smooth and rough strains of pneumococcus), require horizontal gene transfers? A. Yes, but only when just the smooth type cells were used (no rough types involved) B. No. Although some of the strains were virulent, this had nothing to do with viruses C. Yes. The non-virulent rough strain was transformed into killers by horizontal gene transfer D. No. HIV infection is an example of this but bacterial transformation is not E. Yes, because the DNA had to be transcribed into RNA and then reverse transcribed back into DNA 3. If you added radioactive uracil to human cells during the whole time that an HIV infection began and produced new HIV viruses then: A. The radioactivity would kill both the cells and the viruses
