Monday, January 7, 2008. 10-3 Assessment (pg 252 1-5). 1 What chemicals regualate the cell cycle? How do they work? Cyclins regulate the timing of the cell. 2 What happens when cells do not respond to the signals that normally regulate their growth? The form masses of cells called tumors that can damage the surrounding tissues. 3 How do cells respond to contact with other cells? The form a mass. such as cancer. 4 Why can cancer be considered a disease of the cell cycle? Subscribe to: Post Comments (Atom).

Dazzle: Prophase and Centriole
http://dazzlechix26.blogspot.com/2008/01/vocab-7-8.html
Saturday, January 5, 2008. Prophase: the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. Http:/ student.ccbcmd.edu/ gkaiser/biotutorials/dna/mitosis/images/early late prophase1 pc.jpg. Centriole: one of two cylindrical cellular structures that are composed of nine triplet microtubules and form the asters during mitosis.

Dazzle: Cell Cycle and Mitosis
http://dazzlechix26.blogspot.com/2008/01/vocab-5-6.html
Saturday, January 5, 2008. Cell Cycle and Mitosis. Cell Cycle: The series of events involving the growth, replication, and division of a eukaryotic cell. Http:/ www.steve.gb.com/images/science/cell cycle cartoon.png. Mitosis: The process in cell division by which the nucleus divides, typically consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes. 10-3 Assessment (pg 252 1-5).

Dazzle: 10-2 Assessment (pg 249 1-6)
http://dazzlechix26.blogspot.com/2008/01/10-2-assessment-pg-249-1-6.html
Monday, January 7, 2008. 10-2 Assessment (pg 249 1-6). 1 Name the main events if the cell cycle. The main event is that a cell grows, prepares for division, and divides to form two new daughter cells. 2 Describe what happens during each of the four phases of mitosis. Prophase: chromatin condence into chromosomes. The centrioles serperate, and a spindle begins to form. The nuclear membrane breaks down. Anaphase: The sister chromatids serperate into individual chromosomes and are moved apart.

http://dazzlechix26.blogspot.com/2008/01/cytokinesis-and-cyclin.html
Saturday, January 5, 2008. Cytokinesis: the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus. Http:/ img.sparknotes.com/figures/D/d756b5b73abe2974f3521a828791899f/cytokinesis.gif.

http://dazzlechix26.blogspot.com/2008/01/10-1-section-assessment-pg-243-1-5.html
Monday, January 7, 2008. 10-1 Section Assessment (pg 243 1-5). 1 Give two reasons why cells divide. The larger a cell becomes, the more demands the cell places on it's DNA and the more trouble the cell has moving enough nutrients and wastes across the cell membrane. 2 How is a cell's DNA like the books in a library? 3What is the solution to the problems caused by cell growth? They must divide as they grow. 4 As a cell increases in size, which increases more rapidly, it's surface area or it's volume?
