1. F OCUS L ESSON Y OU ARE WORKING ON THE R EAL WORLD EXAMPLE COLUMN 12/04/13 OR 12/05/13 Have your I.D. out for me to check.

2. E SSENTIAL Q UESTION How does meiosis contribute to genetic diversity of organisms? Daily Objectives: SWBAT compare and contrast different types of haploid and diploid cells including gametes, somatic cells, and zygotes. SWBAT explain why meiosis causes genetic variation as a result of crossing over, sorting, and recombining of genes

3. H OW WILL WE GET THERE ? Lab- page 22 DNA replication Homework was due page 23 DNA replication DNA replication activity Quiz #4- DNA replication Corrections/ Enrichment Meiosis notes- pg 27 Meiosis pictures- pg 26 Meiosis lab- pg 28 Home learning- pg 29 Last ClassThis Class

4. H OME LEARNING IS LEARNING! If your notebook is not complete through page 23 you’re behind! Please catch it up! www.edwhitebiology.weebly.com

5. DNA R EPLICATION A CTIVITY Take the card you were given. If you need to review what that is please look on pages 20 and 21 in your notebook. We will now demonstrate the process of DNA replication. ENGAGEMENT LEVEL SHOULD BE 100% Out of your seats please!

6. F IRST Create nucleotides! As many as we can. Remember a nucleotide is a phosphate, 5 carbon sugar, and a nitrogen base Where are nucleotides located within the eukaryotic cell?

7. N EXT Let’s make this strand of DNA: C-A-G What would the complementary strand be? Remember the rules of base pairing!!!

8. N EXT G- T- C These nucleotides should be added. We now have a double strand of DNA. This is in the nucleus of your cells.

9. T IME TO REPLICATE THE DNA When in the cell cycle does DNA replication occur? Synthesis of Interphase What must happen first to our DNA double strand? It must be separated into two strands by the enzyme- Helicase

10. N EXT S TEP - U NZIP THE GENES ! Helicase needs to break the bonds that hold the base pairs together. What are those bonds? Hydrogen Bonds

11. R ESULT 2 separated complementary strands Which enzyme is now going to attach to each template strand to build more DNA? DNA polymerase

12. DNA P OLYMERASE You need to determine which nucleotides in the nucleus need to be added to each template/ strand. Proofread your work!

13. W HAT ARE THE FINAL PRODUCTS ? Results? Two Identical Strands Each containing half of the original and half new Semi-conservative replication

14. Q UIZ #4 DNA REPLICATION - PAGE 25 Clear your desks Volume level zero You will have 10 minutes When you are done turn your quiz over and sit quietly.

15. L ET ’ S GRADE ! Take a colored writing utensil out of your box. Put a check if the answer is right and an X if the answer is wrong. If it is wrong please indicate the correct answer for the student’s paper which you are grading.

16. C ORRECTIONS O R E NRICHMENT PAGE 24 S Statement: What is the correct answer? R Reason: Why is that answer correct? E Evidence: What page in your notebook did you find the correct answer? Use the following DNA segment: ATTCGG Find the complementary strand. Replicate the DNA. Diagram the end products. Describe the enzymes involved. Corrections- 60% or below Enrichment

17. L ET ’ S PREDICT ! T HINK - PAIR - SHARE Why aren’t ALL siblings with the same parents twins? My brother and I look alike, but we are NOT twins even though we have the same parents. Time to learn about MEIOSIS!

18. F OCUS L ESSON Y OU ARE WORKING ON THE D IAGRAM COLUMN - M AKE YOUR PICTURES NICE ! 12/06/13 OR 12/09/13 Have your I.D. out for me to check. Pick up your group’s box!

21. N OTES ON PAGE 27 3 T YPES OF C ELLS IN THE BODY - Gametes- haploid sex cells (eggs, sperm) Somatic cells- diploid body cells that make up most of your body (heart, liver). Zygote- cell that forms when a male gamete fertilizes a female gamete. Which type of cell listed above can not be found in males?

22. A T THE TOP OF PAGE 26 CREATE AND COMPLETE THIS CHART Type of Cell:Synonym:How many sets of chromosomes Example(s) Gamete Somatic Cell Zygote
