ASU Bio 340 Module 1 And 2 Cogbooks
1. In Griffith's experiments, what made the harmless R cells grow capsules when
exposed to heat-killed S cells?
ANS DNA
2. In the Hershey-Chase experiment radioactive Sulfur was used to
ANS Be incor- porated into the phage protein coat because some amino acids contain sulfur
3. The experiments by Hershey and Chase helped confirm that DNA was the hereditary
material on the basis of the finding that
ANS Radioactive phosphorus was found inside the cell
4. If DNA of a particular species was analyzed and it was found that it contains 27 percent of
adenine (A), what would be the percentage of cytosine (C)?
ANS 23% C

5. Four nucleic acid samples are analyzed to determine the percentages of the nucleotides
they contain. Which of the following DNA sample(s) could be dou- ble-stranded DNA?
Sample 1 A(22%), G(28%), T(22%), U(0%), C(28%); Sample 2 A(30%), G(30%), T(0%),
U(20%), C(20%); Sample 3 A(18%), G(32%), T(0%),
U(18%), C(32%); Sample 4 A(29%), G(29%),T(21%), U(0%), C(21%)
ANS Sample 1
6. Your chromosomes are located and they are made of
.
ANS Inside the nucleus, DNA
