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

Molecular Biology & Biochemistry - Biol 8  ---  Homework - not to be turned in // no grade // no credit

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 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, 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
