Let's start with Mitosis
Mitosis occurs when a cell separates the chromosomes in the cell nucleus so that there are two identical and separate sets of nuclei. Cytokinesis occurs afterwards and the nuclei then forms into two identical daughter cells. It sounds difficult but I like to think of it as two wishbones, not the dressing of course but the kind you find in a poultry. So you have WW(wishbone 1) and BB(wishbone 2), someone at the dinner table has an argument and they grab the wishbones from the meat in attempts to finally have some good luck. They just didn't like that segregation of things. Now that mitosis has occurred, the wishbones look like this: WB(wishbone 1) and WB (wishbone 2). As you have noticed the mitosis of the wishbones have now made them identical and different from the wishbones that they were prior to people arriving to eat dinner. This is the integration of things, which in turn again produces two daughter cells that resemble wishbone 1(WB) and wishbone 2(WB). This occurs in a normal cell society.
The stages of mitosis include: prophase, prometaphase, metaphase, anaphase and telophase. During anaphase chromosomes are supposed to split and the sister chromosomes move to opposite sides of the cell. When they fail to do so WB(wishbone 1) will receive two sister chromosomes and WB(wishbone 2) will not receive any sister chromosomes. eg. 47,WBB or 47,WWB(wishbone 1) and 45,W(wishbone 2). The normal number of chromosomes in the human body is 46, if one has less than or more than the normal 46 chromosomes, the chromosomes are considered to be aneuploidy or abnormal.
Aneuploid cells are also associated with cancer cells. New cells generally divide and replace old cells. The Hayflick limit states that the human cell will divide up to appx. 60 times, afterwards cells will cease production or division. This can be referred to society order. Telomeres which are a part of DNA are attached to each end of the chromosomes. Telomeres contain information and protect the chromosome from deterioration. It is the telomeres that become shorten within each new phase of cell replacement or reproduction. Eventually, the cells along with telomeres cease function and die. Just limit the number of movie intake to avoid becoming ill- that's a chick flick move. When cells reach their Hayflick limit and cease to replicate anew they become malignant and die off. As a result the telomeres become smaller and the enzyme telomerase is no longer able to continue life due to the discontinuation of cell reproduction. The telomerase enzyme then develops a malignancy of growth since the cells have changed or mutated in such that they can no longer produce normally because they have ceased to grow and eventually spread to kill other cells.
To replenish those cells that go through flick after flick one should consider supplements that contain xanthones. This would provide the body with the antioxidative activity along with apoptosis needed to prevent the spread of disease and enable a person have those "back in the day" cells; and live to be older than some of the movies I tend to watch.
