Mitosis. Mitosis is the process by which new cells are generated. Mitosis produces 2 genetically identical daughter cells. Overview of Mitosis:. Parent cell. Replicated chromosomes condense at the start of mitosis. Mitosis. Sister chromatids separate and two daughter cells are formed.

Replicated chromosomescondense at the start of mitosis
Sister chromatids separate and two daughter cells are formed.
Parent cell and daughter cell contain thesame complement of chromosomes.
As the chromosomes move toward the poles, the microtubules are broken down at the kinetochore end
Motor molecules "walk" along a microtubule track
Cytokinesis in animals
Pass this checkpoint if:• cell size is adequate• chromosome replication is successfully completed
Pass this checkpoint if:• all chromosomes are
attached to mitotic spindle
Pass this checkpoint if:• cell size is adequate• nutrient availability is sufficient• growth factors (signals from other cells) are present
