Agenda 3/21 Prokaryotic Control Review Eukaryotic Control Review Development Review Homework: Study for Unit Exam
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
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
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
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.
Developmental Review https://www.khanacademy.org/science/biology/developmental- 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
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
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
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
Goal and Prize? What do we want our goal to be? What do we want our prize to be?
