Mitotic Phase

review well my luvvss

Mitotic Phase

• multistep process during which the duplicated chromosomes are condensed, aligned, separated, and moved to opposite poles of the cell, and then are divided into two new identical daughter cells

Mitotic Phase

• actual cell division process/formation of 2 daughter cells

Mitosis & Meiosis

Types of Mitotic Phase

Somatic Cells

Mitosis

Sex Cells (gametes)

Meiosis

Mitosis

• Result in formation of the daughter cells with same amount and kind of chromosomes as the parent cell

• For body cells

Mitosis

• prophase, metaphase, anaphase, telophase, and cytokinesis

Meiosis

• For reproductive cells/gametes

• Cell division that result in the formation of four daughter cell each with half the number of  chromosomes of the parent cell

Karyokinesis

• Movement of nucleus

Karyokinesis

• Only in eukaryotic cells because prokaryotes have no nucleus

• Cytokinesis

• Movement of cell separation

• M Checkpoint

• Spindle Checkpoint

• Occurs near the end of the metaphase stage of karyokinesis

Trisomy 21

Down Syndrome

Spindle Fibers

where sister chromatids should be correctly attached
