1. Agenda 3/21 Prokaryotic Control Review Eukaryotic Control Review
Development Review
Homework: Study for Unit Exam

2. The Operon Play Each person will be given a role
As a class, decide the best way to act out the role
You will have 5-10 minutes to ‘practice’ and then you can model the lac operon for me
Then, we will switch roles and do the trp operon

3. Prokaryotic Control Review Questions
1. Explain what is meant by an inducible and repressible operon.
2. Describe the components of an operon and state their function
3. Explain the state of the lac operon in the presence and absence of lactose
4. Explain the state of the trp operon in the presence and absence of tryptophan

4. Modeling Epigenetics
Using on the materials on the lab station, you will create a model of epigenetics
You must show methylation and acetylation and label all necessary parts

5. Eukaryotic Control Review Questions
1. Why is methylation DNA less likely to be expressed?
2. Explain the role of transcription factors in cell specialization
3. How do spliceosomes and alternative splicing affect gene expression?
4. Describe three difference in gene expression mechanisms between eukaryotes and prokaryotes.

6. Developmental Review
biology/development-and-differentiation/a/introduction-to- development
Use this link to read through as a group
Create a flow chart that includes the words: differentiation, determination, morphogenesis, growth
Add in as many other terms, definitions, or examples you can get from the reading

7. Developmental Review Questions
1. Summarize the role of gene expression during development
2. Compare and contrast differentiation and determination
3. Explain the role of apoptosis during morphogenesis in human development
4. Describe the mechanism of determination and differentiation in human development

8. MC Strategies Annotate the questions
Write down what you know before looking at questions
(Draw out the operon, draw methylation etc.)
Try to answer the question before looking at the answer choices
Do the easy questions first
REALLY try to get the questions right that you understand

9. FRQ Strategies
Underline each key detail
Use as many specific science words as you can
RE READ YOUR ANSWERS- make sure your sentences make sense, your choice of words is correct, it flows logically
Be sure you actually answer the question

10. Goal and Prize? What do we want our goal to be?
What do we want our prize to be?
