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!

Hey, What's on that Mitosis/Meiosis Quiz On Thursday 1/18?

1. Be able to list and describe what happens during the 3 parts of interphase, the phases of mitosis, and cytokinesis (this is like what we did during the yarn table demonstration)
2. Be able to describe the basic process of binary fission.
3. Be able to distinguish between cell division in plant and animal cells.
4. Be able to identify a phase of mitosis in an onion root tip slide.
5. Bel able to describe the function of cyclins and why we are interested in studying them.
6. Be able to calculate mitotic index, given the number of cells in each phase  
7. Be able to identify phases of meiosis, both in a diagram (like the ones on the worksheet) or in a description of what is happening.
8. Be able to describe how crossing over and independent assortment add to an infinite variety of gametes and be able to draw each using colored pencils.

There will be 5-8 multiple choice, a long answer (see number 1 above), 1 onion root tip slide ID, 1 meiosis picture ID, and 1-2 short answers.

Welcome to 2018!!

We have roughly 3 weeks before the end of the semester, so make sure that you are getting your assignments done, check Synergy, and do test corrections if needed.  If you want to do a Book Group, you need to make sure that you plan ahead with your group!  There are 2 remaining SPARK lectures, on on Wed 1/3 and the other on Wed 1/17.

• Wed 1/3:  Cell Respiration and Photosynthesis tests back to look at and then recollect.  This test can be corrected up to 49 points (75%).  To do test corrections, come back in during FLEX and I will give you your test back to correct using your notes, book, or asking questions.  You can earn half credit back for what you missed, so need to correct 10 pts worth if you need 5 points, etc.  Brief overview of Cell Division and start Cell Division Worksheet.  Read 1.6 on Mitosis for homework.
• Fri 1/5:  Notes on the Cell Cycle.  Go over group simulations, practice them, and then do them for me.  Complete the back side of the Cell Division worksheet, except microscope part, which we will do next week.  Do smoking and cancer data based question on pp 58-59 of your text, answering the questions in your notebook.  Read 3.3 on meiosis for homework.
• Tues 1/9:  Do Microscope Identification of phases of mitosis (back side of worksheet).  Turn in worksheet.  Check off DBQ and go over.  Go over the process of meiosis, including crossing over.
• Thurs 1/11:  Finish going over meiosis and do meiosis creature worksheet and group assignment.  Start group posters of creatures.
• Tues 1/16:  Finish meiosis creature posters.  Review mitosis and meiosis for quiz on Thursday 1/18.
• Thurs 1/18:  Quiz on mitosis/meiosis.  Review for final exam.
• Mon 1/22:  Review for Final Exam.
• Wed 1/24:  Finals:  1,2,4
• Thurs 1/25:  Finals 5,6,8
• Fri 1/26:  Finals 3,7
