Mitosis
Steps in cell division
Term | Definition |
---|---|
mitosis | division of the cell nucleus and cell |
interphase | growth and preparation for division |
g1 phase | growth of cell |
s phase | replication of DNA |
g2 phase | preparation for division |
prophase | nuclear membrane starts to disappear and chromosomes condense |
metaphase | chromosomes line up along the middle of the cell and spindle fibers attach |
anaphase | spindle fibers shorten and chromosomes are pulled apart at the centromere |
telophase (animal cells) | chromosomes are at opposite sides of the cell, nuclear membrane reforms and in animal cells membrane pinches in. |
telophase (plant cells) | chromosomes are at opposite sides of the cell nuclear membrane reforms and a cell plate starts to form |
cytokinesis | cytoplasm is divided and two daughter cells are formed |
sister chromatids | duplicated chromosomes that are joined together at a centromere until after mitosis |
