BIO 340: Genetics Exam III (Mangone) 118
Q&A/ Already Graded A+.
What is a gene? - Answer: Fundamental unit of inheritance
Origin of the word "gene" - Answer: greek: genos (origin), and genesis (birth)
Gregor Mendel Experiment - Answer: -pea plants
-traits do not blend in offspring
-traits are discreet, distinct entities
Genetic material is - Answer: nucleic acid
Which of the following statements best represents the central conclusion of the Hershey-Chase
experiments? - Answer: DNA is the identity of the hereditary material in phage T2.
Because phage DNA and not protein was associated with bacteria at the end of the experiment,
it could be concluded that DNA - not protein - must be the genetic material.

What observation did Griffith make in his experiments with Streptococcus pneumoniae? -
Answer: The mouse did not survive when injected with a mixture of live, avirulent (rough)
Streptococcus pneumoniae and heat-killed, virulent Streptococcus pneumoniae.
Something in the heat-killed preparation was able to transform the avirulent strain to a virulent
form.
What results did Avery, McLeod, and McCarty obtain in their experiments with virulent
bacteria? - Answer: DNase destroyed the transforming activity.
Treatment of the transforming principle with DNase destroyed the DNA and thus its ability to
transform bacteria.
T or F: Guanine and adenine are purines found in DNA. - Answer: True
Guanine and adenine are indeed purines found in DNA; thymine and cytosine are the
pyrimidines found in DNA.
What is the complementary DNA sequence to 5′ ATGCTTGACTG 3′? - Answer: 5′ CAGTCAAGCAT
3′
After observing the results of one round of replication, the scientists obtained results from a
second round. The purpose of one additional round of replication was to _______. - Answer:
distinguish between semi-conservative and dispersive replication
The new DNA strand that grows continuously in the 5' to 3' direction is called the - Answer:
leading strand
