McGarrity's

Biology II

What's new in January?

This month we will be exploring gene expression and genetic engineering.


Our objectives:


• Explain why cells regulate gene expression.

• Discuss the role of operons in prokaryotic gene expression.

• Determine how repressor proteins and inducers affect transcription in prokaryotes.

• Describe the structure of a eukaryotic gene.

• Compare the two ways gene expression is controlled in eukaryotes.

• Summarize the role of gene expression in an organism’s development.

• Describe the influence of homeotic genes in eukaryotic development.

• State the role of the homeobox in eukaryotic development.

• Summarize the effects of mutations in causing cancer.

• Compare the characteristics of cancer cells with those of normal cells.

• Explain how geneticists can detect and treat genetic disorders.

• Trace the steps of a Lac operon.

Genetic Engineering Group Project

Students will individual research a particular area of genetic engineering. In groups, they will create a class presentation. This presentation can be made using powerpoint, Prezi, or video.



Student presentations will include:


  • What is genetic engineering?
  • Why are scientists pursuing their topic area of genetic engineering?
  • How their assign topic of genetic engineering is accomplished.
  • Three advantages and disadvantages of this type of genetic engineering.
  • Whether or not they believe their type of genetic engineer is ethical. Why or why not.


Students will be graded on their presentation, individual article summary, and group participation.


Genetic Engineering Project information

Genetic Engineering Assignment – due Jan 23rd A-day and Jan 24th B-day

Research a particular area of genetic engineering (a genetically modified organism)

Create a powerpoint , Poplet, Prezi presentation on your assigned topic

Presentations must be emailed to nicole.mcgarrity@rcsd.ms

by this date: Jan 23rd A-day and Jan 24th B-day

All late presentations will be counted off 20 points per late class period

Come prepared to present everyday starting Jan 23rd A-day and Jan 24th B-day

No EXCUSES!!!

Questions you must answer in your presentation

1. What is genetic engineering and how does it relate to your topic?

2. Why are scientists pursuing your topic area of genetic engineering?

3. Describe how your "type" of genetic engineering is accomplished. Be as specific as you can.

4. Discuss three advantages and disadvantages of this type of genetic engineering.

5. What is your personal opinion of this type of genetic engineering? Do you think it is ethical? Explain with supporting details.

Other requirements:

Have a works cited page with at least three references. Use correct grammar, punctuation, and complete sentences.


Presentation 50 points


You'll be graded on


Content Facts

The project content is exemplary and suggests the student discovered the important ideas of topic. The group expresses their opinion of the topic using facts.



Images

All images are effective.



Style & Organization

Display is interesting and attractive. Materials are complete and organized to present the ideas well.

Materials are complete and well organized. Presentation has sequence and plan evident.



Writing mechanics and resources

Resource list is complete and correct.



Presentation

Stands up straight, looks relaxed and confident. Establishes eye contact with everyone in the room during the presentation. The presentation is clear and concise.

Sometimes stands up straight and establishes eye contact.



Be prepared to share your research with the class for discussion. You will use the smartboard for your presentation. You should have a minimum of 5 pictures in your presentation to complement the presentation. You may use note cards or refer to the smartboard but you may NOT read your notes or your presentation from the board! Make your power point interesting – no long paragraphs on the screen. You may use a website or video clip from the Internet to enhance your presentation or bring in samples for us to look at or enjoy.

BEWARE OF PLAGIARISM – it is easy to detect! If a direct quote is used, it should be limited to two sentences and cited, of course. Any plagiarism results in a zero.

Want your student to improve?

Morning tutoring is available before school from 7:30am to 8:00 am any morning except Tuesday.


Activate your powerschool account, so you can see assignments in advance.

Have your child use quizlet.com to review their vocabulary.

Check out the learning resource page to access your child's online textbook. There you'll find animations, diagrams, and interactive resources.

Make sure your child is creating a self made study guide for their test. Turning it in the day of the test will earn them 5 extra bonus points.


Note Essentials for the gene expression unit

Note Essentials Modern Biology Ch 11 Gene Expression

Use all of the terms to create a study guide for your test. Pull information from your book, notes, handouts, and bellwork. Be sure that you head your paper and number the topics with the same number from this sheet. Turn your note essentials in the day of your test to earn 5 bonus points towards your test. Be sure to see Mrs. McGarrity before school if you have any questions regarding note essential.
