pgs 63-64 Meiosis only information

pg 63 may have some information about mitosis vs meiosis, but is should also have info on just meiosis (probably the table shown below)

pg 64 labeled drawings of meiosis (see picture below)

pg 62 Mitosis vs Meiosis

What is the difference between mitosis and meiosis?  (and why really did biologists name two similar processes so . . . .similar?)

Mitosis vs Meiosis t-chart

Click here for a NOVA animation to help with the differences.  

Please take notes on page 62 (from the above resources)
 
Really corny animation and song!  Meiosis square dance 

Take this quiz and e-mail the results to me (and to yourself)

 

Nova: Can we live forever? (and do we want to?)

As we now know about the cell cycle, the question becomes, why do we care about it and what sort of scientific advances are being made because of our knowledge?

Today we watched a NOVA: Science NOW episode called "Can We Live Forever?"

Test on Cell Cycle objectives Tuesday!!!!

Cell Cycle objective test (see post from Monday March 25th) on Tuesday

You will be allowed ONE 3x5 notecard (front & back) for the test.

Couple of things to consider when studying for the test

• Use the Mader Chapter 9 resources (including the post-test)
• There will most likely be one "calculation" type question on the test (use Campbell Bio Chapt 8 thinking like a scientist to help with that) 

Another great resource for all things biology (and other sciences too)

Cell Cycle info

You will have through Friday to work on the cell cycle learning outcomes (see previous post).

On Tuesday April 2nd, there will be a test on these outcomes.  The test will be very similar to the test found on the Mader site for chapter 9 (click here for the site)

Cell Cycle, Mitosis, Cancer, prokaryotic cell division

pg 53 

Learning Outcomes

The Cell Cycle (info for these outcomes goes on pgs 54-55)

1.    List the four stages of interphase, and describe the major events that occur during each stage in preparation for cell division.

2.    Describe the difference between mitosis and cytokinesis.

3.    List the checkpoints that regulate the progression of cells through the cell cycle.

4.    Explain the mechanisms within the G1 cell cycle checkpoint that evaluates growth signals, determine nutrient availability, and assess DNA integrity.

Mitosis and Cytokinesis (info for these outcomes goes on pgs 56-57)

1.    Explain how the cell prepares the chromosomes and centrosomes prior to nuclear division.

2.    Summarize the major events that occur during mitosis and cytokinesis.

3.    Discuss why human stem cells continuously conduct mitosis.

The Cell Cycle and Cancer (info for these outcomes goes on pgs 58-59)

1.    Describe the basic characteristics of cancer cells.

2.    Distinguish between the roles of the tumor-suppressor genes and protoncogenes in the regulation of the cell cycle.

Prokaryotic Cell Division (info for these outcomes goes on pgs 60-61)

1.    Distinguish between the structure of a prokaryotic and eukaryotic chromosome.

2.    Describe the events that occur during binary fission.

• Use Campbell biology (chapter 8) or the Mader site (chapter 9) for the majority of the info needed
• another Mader site (older edition of the book) also has some great resources (maybe slightly different than the newer edition)
• This page from Biology corner may also be helpful
