n""* l\T^l-0{o KeyZ 1. Your textbook describes two experiments (i.e., Avery, Macleod and Mccarthy - 1944 and Hershey and Chase - 1951) that proved DNA is the genetic material. Indicate which of th€ following statement(s) conectly describes these two experimental approaches. (16pts.) A. Hershey and Chase used radioisotopes of phosphorus (32P) and sulfur (35S) to show that the genetic materials of pneumococcal bacterial was DNA not proteins. o Hershey and Chase showed that shortly after infection with radiolabelled bacteriophage, 35S was found predominately outside the infected bacteria while 32P was found predominately on the inside of the bacteria. The Avery et al experiments showed thu bacteriophage could be transformed into a virulent strain with lipids, polysaccharide or protein. The Avery experiment showed that DNA injected under the skin of mice could cause death. /'-\ ( e. ) fn" Avery et al experiment showed that nonvirulent pneumococci could be transformed \---'l into a virulent strain with DNA. 2. ln 1902, Sutton and Boveri, proposed the Chromosome Theory of Inheritance. Which of the statements below is not consistent wittr- this theory. Indicate your answer by circling the incorrect A\rement. (10 pts. ) /\ I a. '\ The pairing of chromosomes during prophase of meiosis is random' \_-/ B. Genes segregate during meiosis by longiodinal division of each chromosome.
