Mitosis and Cell Cycle

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.

Structure A refers to the _____.

• chromatid
• chromosome
• centromere

Fruit fly body cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have -

• 16 chromosomes.
• 46 chromosomes.
• 8 chromosomes.
• 4 chromosomes.

These structures pull the spindle fibers and attached chromosomes to opposite ends of the cell.

• Spindle fiber
• Centriole
• Nucleus
• Centromere

The stages of mitosis in order

• Metaphase, Anaphase, Prophase, Telophase
• Prophase, Anaphase, Metaphase, Telophase
• Prophase, Metaphase, Anaphase, Telophase
• Anaphase, Prophase, Telophase, Metaphase

Structure (b) is a ____.

• chromosome
• chromatid
• centromere

Structure (c) is a ____.

• chromosome
• chromatid
• centromere

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other.
• different from the starting cell and different from each other.
• identical to the starting cell and different from each other.
• identical to the starting cell and identical to each other.

Mitosis is useful for the creation of new cells which is important for all of the following EXCEPT

• organism growth.
• repair of damage.
• replacement of worn out cells.
• generation of gametes.

Have you ever heard of a skin graft? Skin cells can be harvested from one area and be grown in order to help burn victims or other skin injuries. Which process would result in the development of more skin cells in this treatment? 

• Mitosis
• Meiosis
• Crossing Over
• Interphase
