Question 1
Correct 1.00 points out of 1.00
CHAPTER 16: In his transformation experiments, what did Frederick Griffith observe?
Select one:
a. Mutant mice were resistant to bacterial infections.
b. Infecting mice with nonpathogenic (non-lethal) strains of bacteria makes them resistant to pathogenic (lethal)
strains.
c. Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic (non-lethal) strain can convert
some of the living cells into the pathogenic (lethal) form.
The correct answer is: Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic (non-lethal)
strain can con vert some of the living cells into the pathogenic (lethal) form.

b. the nucleotide sequence of the template strand
c. the primase used in the reaction
d. the particular DNA polymerase catalyzing the reaction

Question 5
Correct 1.00 points out of 1.00
CHAPTER 16: The strands that make up DNA are antiparallel. This means that
Select one:
a. one strand contains only purines and the other contains only pyrimidines.
b. the twisting nature of DNA creates nonparallel strands.
c. the 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.
d. base pairings create unequal spacing between the two DNA strands.
e. one strand is positively charged and the other is negatively charged.
The correct answer is: the 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.
