Answer the following question in 3-5 complete sentences.
Be sure to include KEY vocabulary and PROVE to me you are AP Biology students (in case your forgot over the break)
1. Our civilization generates many potentially mutagenic chemicals (pesticides, for example) and modifies the environment in ways that increase exposure to other mutagens, notably UV radiation. What role should the government play in identifying mutagens and regulating their release to the environment?

A rather large population of Boreal Toads have 239 pink-sided individuals and 647 purple-sided individuals. Assume that pink is totally recessive. Please calculate the following (2 pts. each):
Recessive Genotype:
Dominant Genotype:
The expected genotype frequencies.
The percentage of heterozygous individuals that you would predict to be in this population.

7. Review Question #1
Outline your response to the following question in your notes. You may use bullet points. (5 minutes)
The genetic code is rich with evolutionary implications. For instance, notice that the 20 amino acids are not randomly scattered; most amino acids are coded for by a similar set of codons. What evolutionary explanations can be given for this pattern? (hint: There is one explanation relation to historical ancestry, and some less obvious ones of a “forms-fits-functions” type)
With a partner, form a response to this question in a complete sentence(s). (10 minutes)
Be ready to share out

8. Partner 2
Find someone who is interested in studying the same subject as you in college. If you can’t find the exact same subject, find someone close!

9. Review Question #2
Draw your response to this answer in your notes with your partner. Be ready to share out.
A biologist inserts a gene from a human liver cell into the chromosome of a bacterium. The bacterium then transcribes and translates this gene. The protein produced is useless and is found to contain many more amino acids than does the protein made by eukaryotic cell. Explain why?

10. Pg. 63 Genetic Vocab
Our next unit is GENETICS! We will cover the cell cycle, mitosis, meiosis, Punnett squares, genetic diseases, and back to Chi-Squared!
But first, we need to be experts on vocabulary.

Define the following terms in your notebook on page 63. What you do not finish is HW and I will check it tomorrow.
(22 minutes)
Cell division
Genome
Chromosomes
Somatic Cells
Gametes
Chromatin
Sister chromatids
Centromere
Mitosis
Cytokinesis
Cell Cycle

12. Pg. 64 Cell Cycle
The ability of organisms to reproduce their own kind is the one characteristic that best distinguishes living things from non living matter.
Example?
Viruses cannot replicate on their own! They need a host.
Think back to Virchow (flip to notes)
“Where a cell exists, there must have been a preexisting cell…”
This is cell division
Definition?
The reproduction of cells

13. Pg. 64 Cell Cycle
Plants/Animals
Cell division unites both unicellular and multicellular organisms
Sexual vs. asexual
This is the cell cycle!
Key Point #1: Cell Cycle
The life of a cell from the time it is first formed from a dividing parent cell to division into two cells.
Passes on identical genetic information to daughter cells
This must be regulated, if not= cancer
Bacteria

14. Read page. 219 Concept 12.1

15. Genomes Before a cell can divide, al of the DNA must be copied=
Eukaryotic DNA is 2 meters long!
Before a cell can divide, al of the DNA must be copied=
Replication!
Why?
You do not give away your original! You keep it, and give a copy away.
Why is the statement above not 100% correct? (turn and talk)
The reason why the statement above is not 100% correct is bc of the semi conservative model. We are not actually keeping the original copy. We give away half the DNA strand to the daughter DNA. SEMI Conservative.

16. That is a lot of DNA. How does all of the DNA fit into every cell?
Packed into chromosomes

17. Key Point #2: How many Chromosomes
Somatic Cell
Gametes
All body cells
46 chromosomes
23 from each parent
Sex cells
23 chromosomes

18. Chromosomes
Draw and label in your notebook

19. Concept Check 12.1 Page 220 (Orange book)
Complete the concept check 12.1 in your notes with your partner.

20. Key Point #3: Mitosis is for growth and repair
Today and this week, we are going to focus on mitosis. I just want you to think about growing and repairing throgh the process of mitosis. The key players here are the chromosomes!

21. Mitosis
Key Point #4: In mitosis, a somatic cell creates an exact copy of itself.
Body Cell

22. The Cell Cycle

23. Interphase Key Point #1: Interphase consists of G1, S, and G2 phases.
90% of cell life
Centrosomes duplicates

24. G1
Key Point #2:
Intense cell growth

25. S
Key Point #3:
DNA is replicated

26. G2
Key Point #4:
Cell continues to grow and get ready for division

27. Mitotic Spindle Centrosome: a non- membranous organelle
(organization center for microtubules)
Centrioles are located at the centrosome
Not the most important job
An aster forms to connect at the kinetochore

28. Final Test Corrections
Directions: Begin working on your final test corrections. Test corrections are due Friday. All sections can be corrected. Complete corrections on a separate sheet of paper and staple this paper to the back of your exam.
