Why must most material (such as proteins, lipids, carbohydrates, and new organelles) be produced in the cell body? In other words, why can’t these materials be built right in the synaptic knobs if that is where they are needed?

Explain fast axonal transport, covering the following: How fast is it? What structure in a neuron’s axon is used as a pathway or “train track” for materials to be moved to and from the neuron cell body (soma)? What proteins can travel on this track, and which direction can each go?

What is the name of the part of the kinesin protein that looks like feet? What powers each “step” of the kinesin molecules along the microtubule and how does the “step” then happen?

Rabies virus travels from the motor nerves innervating muscle tissue to the brain. This means that the rabies virus is using which direction of axonal transport? How do you know?

It can take 3 to 12 weeks for the virus to reach the brain. Other sources say it can take 30 to 50 days. If you were bit on the toe by a rabid raccoon, how long would you expect it to take for the virus to reach your brain? If a person is 5'2, use the speed of axonal transport to calculate a rate of travel. We will assume that the virus can find a motor neuron immediately, although it is actually likely that it would several days to a week for the virus to reach synaptic knobs of NMJs. Remember this is on your toe much farther from the brain than the hand or shoulder. Show your work.

  1. In humans, a widow’s peak is recessive.  A purebred mother with no widow’s peak marries and a father with a widow’s peak.  What are the probable genotypes and phenotypes of their offspring?

  1. Assume in an animal that brown is dominant over white. The mother is heterozygous brown and the father is homozygous white. What are the probable genotypes and phenotypes of their offspring?

  1. Albinism is a condition in which pigmentation is lacking. In humans, the result is white hair, nonpigmented skin, and pink eyes. The trait in humans is caused by a recessive allele. Two normal parents have an albino child. What are the parents’ genotypes? What is the probability that the next child will be albino?

  1. Huntington disease is a rare fatal, degenerative neurological disease in which individuals start to show symptoms in their 40s. It is caused by a dominant allele. Joe, a man in his 20s, just learned that his father has Huntington disease.

a. what is the probability that Joe will also develop the disease?

b. Joe and his new wife have been eager to start a family. What is the probability that their first child will eventually develop the disease?
