I have reviewed my child’s activities
and homework for the week of
11/10/08 – 11/14/08.
I understand that is important for
me to make sure that my child is
studying to be prepared for the
Quiz on 11/17/08 and has
completed all assignments this
week.
I understand if my child needs to
retake a quiz that the original
quiz with corrected answers
must be brought to class at the
time of the quiz retake and
quiz retakes usually occur on
Tuesdays afterschool.

Help Wanted
Positions Available in the genetics industry. Hundreds of entry-level openings for tireless workers. No
previous experience necessary. Must be able to transcribe code in a nuclear environment.
Accuracy and Speed vital for this job in the field of translation. Applicants must demonstrate skills in
transporting and positioning amino acids. Salary commensurate with experience.
Executive Position available. Must be able to maintain genetic continuity through replication and control
cellular activity by regulation of enzyme production. Limited number of openings. All benefits.
Supervisor of production of proteins—all shifts. Must be able to follow exact directions from doublestranded template. Travel from nucleus to the cytoplasm is additional job benefit.
b) Applicants for the first job of the Help Wanted ad in the table above "Position Available," could
qualify if they were ______________________________.

Extra Credit
The diagram on the right shows Rosalind Franklin X-ray diffraction image of
DNA. How did this evidence affect the work of Watson and Crick?
a) It was used to indentify the four bases that make up DNA.
b) It was used to determine the physical structure of DNA.
c) It was used to develop the theory of independent assortment.
d) It was used to show that DNA was the molecule of inheritance.
Although there are limited numbers of amino acids, many different types of proteins exist because the
a) size of a given amino acid can vary.
b) chemical composition of a given amino acid can vary
c) sequence and number of amino acids is different.
d) same amino acid can have many different properties.
A scientist puts nucleotide chains of UUUUUU in a test tube under conditions allowing protein
synthesis.
Soon the test tube is full of polypeptide chains composed of only the amino acid phenylalanine.
What does this experiment indicate?
a) The amino acid phenylalanine is composed of uracil.
b) UUU codes for the amino acid phenylalanine.
c) Protein synthesis malfunctions in test tubes.
d) Most proteins contain only one type of amino acid.
