Cell Cycle, Mitosis and Meiosis CUA Review

Cells spend most of their lives in which phase?

• Interphase

• Prophase

• Telophase

• Metaphase

Cells of organisms must replicate for?

• Growth

• Replacement of dying cells

• Repair of damaged cells

• All of the above

What is the correct order of the phases of mitosis?

• Metaphase, Anaphase, Prophase, Telophase,

• Pelophase, Motophase, Anaphase, Trophase

• Prophase, Metaphase, Anaphase, Telophase

• Telophase, Anaphase, Prophase, Metaphase

The G1, S, and G2 are parts of which phase of the cell cycle?

• Prophase

• Interphase

• Telophase

• Anaphase

How many chromosomes does a human somatic (body) cell have?

• 46

• 23

• 42

• 26

How many chromosomes does a human egg or sperm (gamete) cell have?

• 23

• 46

• 42

• 26

Daughter cells created by meiosis II have

• half the parents DNA

• exact copy of the parent's DNA

• twice the parent's DNA

• created their own DNA from scratch

What is "crossing over"?

• The exchange of genes between chromosomes during meiosis that results in genetic diversity.

• Programmed cell death (cell suicide) to prevent the spread of mutated/cancerous cells.

• A type of cell division that creates gametes (sperm and egg cells).

• A type of cell division that results in two daughter cells each having the same number of chromosomes as the parent cell.

Is interphase a part of Mitosis?

• Yes, it happens after prophase

• No, it happens before mitosis

What is the end product of Mitosis?

• One daughter cell

• Two identical daughter cells

• Two different daughter cells

• Three identical daughter cells
