Mitosis Flashcards

The primary result of mitosis is the transferring of the parent cell's genome into two daughter cells. These two cells are identical and do not differ in any way from the original parent cell. Mitosis occurs in our heart, liver, brain, skin, blood and more. Why is Mitosis so important?

1047414865InterphaseChromosomes are copied. Chromosomes appear as threadlike coils at the start, but each chromosome and its copy change to sister chromatids at the end of this phase.
1047414866ProphaseMitosis begins as centrioles appear and begin to move to opposite ends of the cell. Spindle fibers form between the poles.
1047414867MetaphaseChromatids attache to the spindle fibers. The chromosomes line up along the middle of the cell.
1047414868AnaphaseChromatids separate and begin to move to opposite ends of the cell, pulled along by the spindle fibers
1047414869TelophaseCell membrane moves inward to create two daughter cells - each with its own nucleus with identical chromosomes.
1047414870CytokinesisTwo new nuclei form. Chromosomes appear as chromatin. Mitosis ends.
1047414871CentromereThe most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.
1047414872MitosisCell division in which the nucleus divides into two nuclei containing the same number of chromosomes with an end result of two identical cells.
1047414873Nucleusa part of the cell containing DNA and RNA and responsible for growth and reproduction
1047414874Spindle FibersSpecial microtubules made of proteins which connect to centromeres and pull apart chromosomes.
