Mitosis and Cancer: P1

In human beings, mitosis is necessary for...

• duplicating cells and repair of tissues.

• formation of the gametes, or sex cells.

• reproduction of another individual.

• reducing the number of chromosomes.

Interphase:

• occupies the majority of the cell cycle

• includes DNA replication

• includes growth of cell

• all are correct

Which of the following statements is NOT a characteristic of cancer cells?

• Uncontrolled growth

• Disorganized cell layers

• Normal nuclei (plural for nucleus)

• Do not undergo cellular death (or apoptosis)

The process by which the nuclear material is divided equally between two new cells

• mitosis

• cancer

• spindle

• centromere

Cancer cells typically form a mass of tissue called a _______________.

• biopsy.

• carcinogen.

• tumor.

• allergy.

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

• 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.

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.

What is cancer?

• The heart does not receive enough blood.
• Sudden disruption of blood flow to part of the brain.
• Blood filled weak spot.
• Uncontrolled growth and spread of abnormal cells.

The phase in mitosis where chromosomes move away and are pulled apart by spindles to opposite sides of the cell.

• Anaphase

• Cytokinesis

• Telophase

• Metaphase

The phase in mitosis where chromosomes line up in the middle of the cell.

• Cytokinesis

• Interphase

• Anaphase

• Metaphase
