The hereditary material of the nondividing or interphase cell is contained in a compact body, the nucleus. Most nuclei divide (reproduce) by a process called mitosis. Near the nucleus in animal cells are two small bundles of rods, the centrioles, which lie at right angles to each other.
As division begins, the centrioles seperate and move to opposite poles of the cell. As the centrioles move, they are surrounded by a system of micro tubes, the asters. At the same time the nuclear membrane disintegrates and the nuclear material condenses and coils to form visible chromosomes. Each chromosome is divided lengthwise into two sister chromatids which are joined at a constriction called the centromere. Microtubules connect the centromeres of each chromosome to the centrioles, and the chromosomes then move to the equatorial plane of the cell (equidistant from the centrioles). The sister chromatids seperate and are then called daughter chromosomes.
The daughter chromosomes begin moving toward opposite centrioles. When the chromosomes stop moving, a re-organization takes place which usually involves cytoplasmic division and nuclear reformation. This produces two interphase (daughter) cells. During the interphase, each chromosome reproduces itself; thus, new sister chromatids are present for the next division.

i was just wondering if anyone can see the background pic?
Senator John Kerry: Are you nuts? Are you trying to push a socialized medicine program? You are a SOCIALIST, aren't you? As a taxpayer, I DO NOT want my money paying for the government and its stupidity. CUT taxes and let me make my own choices! Quick trying to "help" those who seem to not want to help themselves, AND DO NOT give me the BS about them not able to help themselves. They are in their situations because of what the government has done to try and help them. Does this really make sense to you? Think about it!
By the way, Pres. Bush, why don't you begin to phase out Medicare and give the money back to the taxpayers?

A Priest was in his room and realized that his rooster was
missing. He decided to bring it up in Sunday Mass. Right before
the sermon the Priest asked, "Who has a cock?" All of the men in the room stood up. The Priest said, "No, No, No. Who has seen a cock?" All of the women in the room stood up. The Priest said, "No, No, No. Who has seen MY COCK?" All of the nuns stood up.
Sorry to those church people, but this is hilarious.
