We will tell you this
Indicate your answers in the test book. Leave no questions blank.
1) Please place your ID prominently on your desk and sign the
attendance sheet when it comes to you.
2) There are 12 pages in this test. Check your paper carefully.
3) There is only one fully correct answer for each question. Part
marks may be awarded. Answer all questions. We do not
subtract wrong from right.
4) Indicate your answers in both the test paper and on the
Scantron.
5) It is your responsibility to transfer all answers from the test
book to the Scantron sheet within the 2 hour test period.
6) When finished, please stay seated and raise your hand.
We will collect both your test book and Scantron sheet.
Warning
The Scantron marking program has a cheating analysis feature that compares answer patterns for all papers.
It alerts us to similarities. We then check seating arrangements.
Do not sit near your study partners or write the same test codes. Keep your work directly in front of you.
Please help us avoid any and all misunderstandings during these tests
Clarifications: Please defend your arguments on this page only. Comments will not be accepted after the test.

Circle the best single letter choice for each of the following questions before
transferring your answers to your computer sheet.
Note: Questions may have 3, 4 or 5 choices.
1. Its particular evolutionary relationship with other organisms is one reason that
Chlamydomonas is such a useful experimental organism.
Which of the following descriptions of Chlamydomonas evolutionary relationships
is correct?
A. Chlamydomonas is only distantly related to any multicellular organism.
B. Chlamydomonas is more closely related to plants than to animals.
C. Chlamydomonas is single-celled; therefore it is closely related to Bacteria.
D. Chlamydomonas diverged from the lineage leading to fungi about 6 billion years ago.
2. The table below shows comparative genomic data for three organisms
(Mb = million base pairs).
E. coli
Chlamydomonas
Human
Genome size
4 Mb
120 Mb
3,000 Mb
Protein coding genes
4,000
15,000
20,000
Assuming that the coding region of a typical gene is roughly the same length in all
organisms, which of the following genomes has the lowest proportion of non-coding DNA?
A. E. coli
B. Chlamydomonas
C. Human
3. To make things easier, scientists tend to use only one of the two different mating types of
Chlamydomonas when doing most experiments in the laboratory.
Which of the following topics could NOT be studied using this approach?
A. DNA replication
B. Heterozygote advantage
C. Chromosome segregation during mitosis
D. Phenotypic consequences of mutated genes
4. Pigments used to harvest light are not freely floating in the cytoplasm; they are bound to
proteins.
With respect to light being used as an energy source, which of the following is a
consequence of having pigments bound in such pigment-protein complexes?
A. Efficient energy transfer from one pigment molecule to another.
B. Increased ability of light absorption to be used for heat generation.
C. Increased number of possible conjugated arrangements of the pigment.
D. A change in shape of the protein upon light absorption by the pigment.
