Name____________________________________________________ 2 1 . Your textbook describes two experiments (i.e., Avery, MacLeod and McCarthy —1944 and Hershey and Chase — 1951) that proved that DNA is the genetic material. Indicate which of the following statement(s) correctly describes these two experimental approaches. (9 pts.) A. Hershey and Chase used radioisotopes of phosphorus ( 32 P) and sulfur ( 35 S) to show that the genetic material of the pneumococcus bacteria was DNA not proteins. B. The Avery experiment showed that non-virulent pneumococci could be transformed into a virulent strain with DNA. C. The Avery experiments showed that bacteriophage could be transformed into a virulent form with lipids, polysaccharide or protein. D. The Avery experiment showed that DNA injected under the skin of mice could cause death. E. Hershey and Chase showed that shortly after infection with radio-labeled bacteriophage, 35 S was found predominately outside the infected bacteria while 32 P was found predominately on the inside of the bacteria. 2 . In 1902, Sutton and Boveri, proposed the Chromosome Theory of Inheritance. Which of the statements below is not consistent with this theory. Indicate your answer by circling the incorrect statement. (10 pts.) A. Genes are arranged in pairs along the length of homologous chromosomes. B.
