You
are
responsible for
Amino Acid and Protein Structure & Function. Your primary
resource is Dr. DeWitt’s class notes on Amino Acids and Proteins. The PPAO
will be given on the date listed at the Due Dates Website. There will be no
retakes.
Your grade on this exam is final. This exam will count 23% of
your
trimester 2 grade.
Exam Format:
The format
of the PPAO will
be a
combination of:
- TWO
essays: Two
from the questions listed below.
You
should plan your answer to each essay so that you can write it within
20
minutes. Each essay will count for 35 points.
- TEN
multiple
choice
questions
(See the Protein Practice Questions handout
provided by Dr. DeWitt in class.) that include the material covered by
these QFYC listed below. You should leave 20 minutes to
answer these
questions
during the exam. These questions count for 30 points of the 100
