Molecular Biology & Biochemistry review quiz (no credit) NAME:
1. What is the probability of two normal parents having a child with
Tay Sachs after having one afflicted child?
2. What is the probability of this couple having two more children
in
a row with Tay Sachs?
3. What is the probability that this couple will have a child with
Tay
Sachs after having three afflicted children?
4. What is the probability that you are a female?
5. What is the probability that you are a male?
6. What is the pH of fresh distilled water? [approximate, if
necessary]
7. What is the pH of distilled water that has been sitting open in a
room for a while? [approximate, if necessary]
8. For each of the following, indicate whether it is likely to
dissociate
completely (or to a large extent) = YES (Y), or virtually not at all =
NO (N); and whether the pH of an aqueous solution of it is likely to be
>pH 7, <pH 7 or » pH7:
9. T/F: "I have fulfilled the prerequisites for this course"
10. The adhesive and cohesive properties of water are due primarily
to

Homework - not to be turned in // no grade // no credit
do not hand in
Using whatever sources you wish, including your textbook for this class
& the one for your chemistry class, find the following information:
1. For each of the following elements, find its electronegativity
& its Van der Waals contact radius. A chart or table would be
a convenient way to display the information.
H C
N S
P O
Why do you think these particular elements were chosen?
2. Find the bond length & bond energy (calories not joules)
for each of the following (again, a table would be helpful; why were
these chosen?) [note: assume un-named bonds are protons]
C-C C=C
C-O
C-H C-N
C=N O-H
O=O P-P in ATP
C-P in ATP [if you can find it]
3. Do you think that the C-C bond length would be longer,
shorter, or the same comparing the following. Be prepared
to explain (this or similar questions). Why is this important?
N-C-C C-C-C
O-C-C
4. Find and define vocabulary in Chapter 1 of the textbook.
These are typically the terms in headings and/or emboldened. As
you peruse the chapter, pick out any terms with which you are not
familiar and look them up as well.
Recognize the names of the organisms mentioned in Chapter 1, and their
classification, e.g. prokaryote or eukaryote; plant, animal, fungi, or
protist; and fundamental chemistry and thermodynamics concepts reviewed
in this chapter.
Be prepared for a quiz on this vocabulary, cell structure, the main
distinctions between prokaryotes and eukaryotes, and these
organism classifications and fundamental chemistry and thermodynamics
concepts from this chapter, as well as other material from this
homework assignment.
Note: for this and all assignments, think about why the questions
were asked or the assignment given. Sometimes similar (or even
identical) questions appear on quizzes and exams. Sometimes this
is a way to prepare for class. Sometimes the assignment purpose
is to expand your horizons...
