,(1.1) In Griffith's experiments, what made the harmless R cells grow capsules when exposed to heat-
killed S cells? - Correct Ans: DNA
(1.1) In the Hershey-Chase experiment radioactive Sulfur was used to: - Correct Ans: Be incorporated
into the phage protein coat because some amino acids contain sulfur
(1.1) The experiments by Hershey and Chase helped confirm that DNA was the hereditary material on
the basis of the finding that: - Correct Ans: Radioactive phosphorus was found inside the cell

(A), what would be the percentage of cytosine (C)? - Correct Ans: 23%
(1.1) Four nucleic acid samples are analyzed to determine the percentages of the nucleotides they
contain. Which of the following DNA sample(s) could be double-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%) -
Correct Ans: Sample 1

3'? - Correct Ans: 4 Amino Acids
, (1.2) What is the correct sequence of steps in the central dogma? - Correct Ans: DNA-->RNA-->Protein
(1.2) Where does translation take place in eukaryotic cells? - Correct Ans: Cytoplasm
(1.2) Where does transcription take place in human cells? - Correct Ans: Nucleus

Correct Ans: 5'-AUGGCCGGUUAUUAAGCA-3'
(1.2) In which of the following pairs do both evolutionary processes introduce new genetic variation into
a population? - Correct Ans: Mutation and gene flow
(1.2) Mutation can be defined as the addition of genetic variation that increases the hereditary diversity
of a population. - Correct Ans: True
(1.2) If an allele has a frequency of 1: - Correct Ans: It is found in 100% of the population
(1.2) When male lions reach sexual maturity, they leave their group in search of a new pride. This can
alter the allele frequencies of the population through which of the following mechanisms? - Correct
Ans: Gene flow
(1.2) When closely related individuals mate with each other, or inbreed, the offspring are often not as fit
as the offspring of two unrelated individuals. Why? - Correct Ans: Inbreeding can bring together rare,
deleterious mutations that lead to harmful phenotypes.
(1.2) Which statement about analogies is correct? - Correct Ans: They are derived by similar
environmental constraints.
(1.2) What do scientists use to apply cladistics? - Correct Ans: homologous traits
