Genetics Test on Monday, March 5th!

This is what will be on the Genetics Test.  Make sure that you study these concepts and come in for help during FLEX this week if you need it.

• Part I:  20 or so multiple choice questions on all kinds of topics.  We will play some Kahoot to help identify the types of questions
• Part II:  a) Chi-Squared Problem.  You will be given the equation and critical value chart, but you will need to know how to calculate expected values, do the math for the equation, and interpret the results.  
• b)  Dihybrid cross that will involve identifying the gametes, filling in the Punnett Grid, and listing the ratios of the results 
•  c)  Describe the genetic cause, symptoms, treatment, and interesting facts for a genetic disorder.  Out of hemophilia, sickle cell anemia, Down Syndrome, Turner Syndrome, cystic fibrosis, and Huntington's.  We will draw 3 of these from a "hat" and you will write about one.  The University of Utah site (Learn Genetics) linked on my website has good info on all of them except hemophilia, and hemophilia is written up in the book (pp 180-181). 
• d)  A short question on a pedigree problem 

Genetic Disorder Poster Project (due Wed, 2/21)

For your genetic disease, find and present the following information on a poster!!

1. I recommend using Learn Genetics Website (except for Hemophilia and Duchenne’s Muscular Dystrophy)
2. Type of inheritance (chromosomal, single gene, dominant, recessive, sex-linked, etc).  Include all that apply.
3. Describe what it does to the body in terms of biochemistry
4. List symptoms, treatments, patient prognosis
5. Interesting Facts
6. Other?

First 2 Weeks of the New Semester

• Wed 1/31:  Final Exams, look at them, and then recollect.  Go over what we will cover 2nd semester.  Start 3.1 and 3.2 book work.  Please finish through the 3.1 questions on your own time if you are not there yet.
• Fri 2/2:  Review 3.1 concepts and questions.  Any questions on 3.2 so far?  Video on Mendel.  Work on 3.2 questions, answering them in your notebook.  Get them checked off if you complete them today.  Otherwise get them checked off on Tuesday.  Read 3.4.
• Tues 2/6:  Check off 3.1 and 3.2 questions and go over.  Types of genetic problems:  Punnett grids, problems with codominance, X-linked problems.  Start genetic problems from the old text book.  
• Thurs 2/8:  More on genetics problems.  Dihybrid crosses.  Work on genetic problems.  Due next Wed 2/14.

3.1 and 3.2 Bookwork for 1/31 and 2/2.

In the past, we have not formally gone over these sections, but I found that some students were at a disadvantage from not going over these concepts.  Please answer the following questions in your notebook.  They will be checked off on Tuesday 2/6.

1. This is in 3.1. What is a gene?
2. Where are genes located?  Draw a diagram to help explain.
3. Look at the chart on p. 142 that compares numbers of genes in different species.  Which species has the most genes?  The least?  How many genes do humans have?
4. Discuss the above information.  Is it surprising?  Why don't humans have more genes than other organisms?
5. What are alleles?  Describe the differences between different alleles.  Where do these differences come from?
6. Do the DBQ on p. 145.
7. Read the section on sickle cell anemia and outline the genetic change that causes sickle cell and what it does to the blood cells and health of people suffering from sickle cell.
8. What is a genome?
9. Describe the carrying out and results of the Human Genome Project.
10. Now we're in 3.2.  Describe the bacterial chromosome.
11. What is a plasmid and where can it be found?  Are they replicated like the main bacterial chromosome?  Explain.
12. Describe the autoradiography technique used to measure DNA molecules.
13. Describe eukaryote chromosomes.
14. What are homologous chromosomes and where do they come from?
15. Do the DBQ on p. 153.
16. Look at the chart on p. 154 comparing genome size.  How is this comparison different from one that you looked at on p. 142?  Is it showing the same thing?  Are the results similar?
17. What is the difference between a haploid nucleus and a diploid nucleus?  Use humans as an example.
18. Explain why different species have different numbers of chromosomes.
19. Do the DBQ on p. 156.
20. What is the difference between an autosome and a sex chromosome?  How many autosomes do humans have?  How many sex chromosomes?
21. Discuss how the sex chromosomes determine sex in humans.
22. What is a karyogram?
23. How can karyograms be used to determine sex and diagnose chromosomal disorders in humans?
24. Do the DBQ on p. 159.

Welcome to Semester 2!

What will we by studying this semester?

1. Genetics!  Including general terminology, the Human Genome Project, genetics problems, Punnett Grids, pedigree problems, genetic disorders and genetic testing, gene mapping, etc.  Textbook sections 3.1, 3.2, 3.4, 10.1 and 10.2.
2. Replication, Transcription, and Translation.  Describe the processes of DNA replication, DNA transcription, and translation (protein synthesis).  Included will be some history of these discoveries, chromosome structure, the genetic code, and protein structure.  Textbook sections 2.7, 7.1, 7.2, and 7.3.
3. Enzymes!  The structure and function of enzymes, including an inquiry lab on the enzyme, catalase.  Textbook sections 2.5 and 8.1.
4. Biotechnology.  Topics will include stem cells, cloning, genetic modification, PCR, and gel electrophoresis.  We will do a gel electrophoresis lab.  Textbook section 3.5, a bit of 1.1 and some excerpts from chapter 7.
5. Plants!  Includes structure, transport, growth, and reproduction.  Textbook sections 9.1-9.4.

Final Exam Expectations

Just a reminder of some basic final exam expectations.  I take Final Exams very seriously and don't want to have any misunderstandings during these 3 days.

• You need to stay in the classroom the whole time!  Go to the restroom BEFORE the test!!
• No phones out AT ALL!  Laptops are ok if you are using it for academic purposes.  
• Bring a book or something quiet to do if you are a fast test taker.
• 
  
• No talking.  We need a quiet respectful test environment.
• No questionable behavior, like looking at  your neighbor’s test.
• Remember that any form of cheating will result in a 0 for the final.  It is not worth it!
