Part 1: Developmental Genetics
Questions to answer:
1. Define the term “differentiation.”
2. Explain the function of each of the following as relates to the process of differentiation:
a. cytoplasmic determinants
b. cellular induction
3.
4.
5.
6.
c. cellular determination
Why does determination have to precede differentiation?
How do cells acquire positional information about their location in a developing embryo?
Explain the function of bicoid.
What are the homeobox genes? What do they do in a developing animal?
Things you should make sure you understand:
(feel free to ask questions about them in class)
Part 2: Genomics
Questions to answer:
1. Explain the purpose of the Human Genome Project (HGP).
2. Compare the approaches to genome sequencing taken by the public human genome project, and
Craig Venter’s private initiative.
3. Explain why the HGP finished sequencing four years ahead of schedule.
4. What is bioinformatics and why is it a necessary and important field of study?
5. Is there any particular pattern among genomes and the organisms who have them?
6. Explain what transposable elements are and give an overview of their function.
7. On a percentage basis, what type of sequence comprises the most of the human genome? What
type of sequence comprises the least?
8. What is a gene family? How do they evolve?
9. Compare identical-sequence and non-identical sequence gene families.
10. Explain the types of signatures that have been left in the human genome when looking at our split
from rodents and from chimpanzees.
11. Why does duplication of genetic sequences typically precede divergence of those sequences?
