Phases of Mitosis

What is mitosis?

• A type of cell division in which one cell divides to produce two new cells that are genetically identical to itself

• A type of cell division in which one cell divides to produce two new cells that are genetically different from itself

• A type of cell division in which one cell divides to produce four new cells that are genetically identical to itself

• A type of cell division in which one cell divides to produce four new cells that are genetically different from itself

What is the purpose of mitosis?

• To ensure that each daughter cell gets a perfect, full set of chromosomes

• To ensure that each daughter cell gets a random set of chromosomes

• To ensure that each daughter cell gets too few or too many chromosomes

• To ensure that each daughter cell gets no chromosomes

What happens during prophase?

• The chromosomes start to condense and the mitotic spindle begins to form

• The sister chromatids separate from each other and are pulled towards opposite ends of the cell

• The nuclear envelope breaks down and the chromosomes are fully condensed

• The spindle disappears, a nuclear membrane re-forms around each set of chromosomes, and a nucleolus reappears in each new nucleus

What happens during metaphase?

• The chromosomes start to condense and the mitotic spindle begins to form

• The sister chromatids separate from each other and are pulled towards opposite ends of the cell

• The chromosomes line up at the metaphase plate, under tension from the mitotic spindle

• The spindle disappears, a nuclear membrane re-forms around each set of chromosomes, and a nucleolus reappears in each new nucleus

What happens during anaphase?

• The chromosomes start to condense and the mitotic spindle begins to form

• The sister chromatids separate from each other and are pulled towards opposite ends of the cell

• The chromosomes line up at the metaphase plate, under tension from the mitotic spindle

• The spindle disappears, a nuclear membrane re-forms around each set of chromosomes, and a nucleolus reappears in each new nucleus

What happens during telophase?

• The chromosomes start to condense and the mitotic spindle begins to form

• The sister chromatids separate from each other and are pulled towards opposite ends of the cell

• The chromosomes line up at the metaphase plate, under tension from the mitotic spindle

• The spindle disappears, a nuclear membrane re-forms around each set of chromosomes, and a nucleolus reappears in each new nucleus

What is cytokinesis?

• The division of the cytoplasm to form two new cells

• The division of the nucleus to form two new cells

• The division of the chromosomes to form two new cells

• The division of the cell membrane to form two new cells

How does cytokinesis occur in animal cells?

• By pinching the cell in two with a band of filaments made of actin

• By forming a new wall down the middle of the cell

• By splitting the chromosomes into two sets

• By elongating and pushing apart microtubules
