an order sequence of events in the life of a cell
Cell division in which the nucleus divides into 2 nuclei containing the same number of chromosomes
Four stages of mitosis
The first and longest phase of mitosis, during which the chromosomes become visible and the centrioles (centrosomes in diagram) separate and move to the opposite sides of the nucleus. The nuclear membrane breaks down during this phase.
The second phase in mitosis in which the duplicated chromosomes (chromatid couples) line up along the equatorial plate of the spindle (down the middle of the cell).
The third phase of mitosis , the chromatids of each chromosome separate/ split at the centromere and move APART towards the opposite ends of the cell
The fourth and final stage of mitosis, in which two identical nuclei are forming, the cell begins to pinch inward and the spindle fibers disappear.
Division of cytoplasm and its contents
A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells.
Combination of DNA and protein in nucleus.
Duplicate copies of DNA, attached at a centromere; distributed to daughter cells
Area where the two copies of a chromosome (sister chromatids) are attached.
A period during which the cell grows, copies its organelles and DNA, and stores energy in preparation for division
The first growth stage of interphase in which cell grows and performs its normal functions. It is also the time in which organelles get copied.
The portion of interphase during which DNA is replicated (copies).
The second growth phase of the cell cycle. The cell grows more and stores energy in preparation for cell division (mitosis)
