In this second Mitosis lesson, Professor Wolfe adds in the terms for the phases of Mitosis. He begins with a quick review of chromatins, chromosomes, and chromatids, and then introduces the five phases of mitosis, which are prophase, prometaphase, metaphase, anaphase, and telophase. Professor Wolfe explains each phase in depth, showing images of example cells and pictures of actual cells to help you understand. Throughout the process, centrosomes start to seperate and the cell forms sister chromatids, the nuclear envelope breaks down, chromosomes line up along the center of the cell, chromosomes seperate, a cleavage furrow forms, and the cell begins to divide.

This lesson is perfect for review for a CLEP test, mid-term, final, summer school, or personal growth!

Taught by Professor George Wolfe, this lesson was selected from a broader, comprehensive course, Biology. This course and others are available from Thinkwell, Inc. The full course can be found at http://www.thinkwell.com/student/product/biology. The full course covers evolution, ecology, inorganic and organic chemistry, cell biology, respiration, molecular genetics, photosynthesis, biotechnology, cell reproduction, Mendelian genetics and mutation, population genetics and mutation, animal systems and homeostasis, evolution of life on earth, and plant systems and homeostasis.

George Wolfe brings 30+ years of teaching and curriculum writing experience to Thinkwell Biology. His teaching career started in Zaire, Africa where he taught Biology, Chemistry, Political Economics, and Physical Education in the Peace Corps. Since then, he's taught in the Western NY region, spending the last 20 years in the Rochester City School District where he is the Director of the Loudoun Academy of Science.

Besides his teaching career, Mr. Wolfe has also been an Emmy-winning television host, fielding live questions for the PBS/WXXI production of Homework Hotline as well as writing and performing in "Football Physics" segments for the Buffalo Bills and the Discover Channel.

His contributions to education have been extensive, serving on multiple advisory boards including the Cornell Institute of Physics Teachers, the Cornell Institute of Biology Teachers and the Harvard-Smithsonian Center for Astrophysics SportSmarts curriculum project. He has authored several publications including "The Nasonia Project", a lab series built around the genetics and behaviors of a parasitic wasp.

He has received numerous awards throughout his teaching career including the NSTA Presidential Excellence Award, The National Association of Biology Teachers Outstanding Biology Teacher Award for New York State, The Shell Award for Outstanding Science Educator, and was recently inducted in the National Teaching Hall of Fame.

hey squidward.

[BestsChanels]

there is no more promethaphase doc.!

[theDaRkEstBLACK96]

NOOOOOOOOOOOO i need more!!!!

[smashingpumpkinsxD]

I've just bought this whole series, and, HOLY SHIT! It's amazing how he explains everything... It's worth the 20 bucks that you'll spend if you buy it.

2:01 repeatedly :D:D

[rohannesburg]

I can't seem to find the answer to this question during Mitosis: Do they Cleaved Chromatids are separated into the different sides during Telophase, do they duplicate to resemble the same amount of chromosomes, or are they just left as sister chromatids?

[diiiva2001]

Also, isnt the differences between Mitosis and Meiosis is that:

1. Corssing over in meiosis (exchange of information)

2. Meiosis produce 4 haploid cells, while Mitosis produces 2 haploid (daughter) cells.

3. Meioss happens in the ovaries and testis, ie sex cells

4. While Mitosis happens in every cells. it is a cell diviision for eurokaryotic cells.

Or is there more? :D I have my big IB- exams tomorrow :) wish me luck
