Transcript of Mitosis

Mitosis is important because it is the reason we are alive, without mitosis our cells would not be able to reproduce and we not be here.
Mitosis is caused by the mother cell reproducing into two daughter cells. Prophase Mitosis and Cell Processes Prometaphase The mitotic spindle is formed and the chromosomes are attached to the microtubules.

What does that mean?
The chromosomes that were condensed in the past stages are connected to a newly formed mitotic spindle. Anaphase The sister chromatids separate and are moved toward to the spindle.

What does that mean?
The DNA is separated and moved towards the spindle in two different parts. Metaphase All of the chromosomes are attached to the microtubles in metaphase. Telophase The mother cell is physically into two daughter cells Mitosis is the process by which a strand of DNA replicates itself. What is mitosis? What causes mitosis? Mitosis is caused by the mother cell dividing into two daughter cells. What compounds are used, made, produced in/by/or with your process? Two daughter cells are produced in the process of mitosis. The chromosomes become condensed and key proteins begin to divide. Chromosomes- a double rod of condensed chromatin
Chromatin- the combination of DNA and proteins that make up the contents of a nucleus Spindle fiber- protein structures that pull apart the genetic material in a cell when the cell divides Now let's break it down Bibliography Arizona University.

Web. 14 Jan. 2013. Examples of Mitosis: All cells except reproductive cells in a multicellular organism undergo mitosis. Mitosis is what makes growth and development possible. Without mitosis, people could not be able to grow and no new cells would be created. If mitosis got out of control, cancer would occur. This is why we should be thankful for mitosis. Now let's see what you've learned. 1. What is produced during the cell cycle? (mitosis)

2.How many main phases is the cell cycle (mitosis) divided into?

3.What are the first three phases?

4.What are chromosomes?

5. Why is mitosis important?
A. 2 daughter cells

A. 5 phases

A.prophase, metaphase, anaphase

A. a double rod of condensed chromatin

A. it is the reason we are alive; without it we wouldn’t grow. We hope you liked our presentation. Thanks for watching. Brought to you by: Shruthi, Atherv, Nick, Abby, Laxmi, Mitchell, and Jackie
