Cell Cycle, Meiosis, Karyotype RETAKE 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

What is cytokinesis?

• When 2 cells merge together to make 1 giant cell

• The end of the cell cycle when the cell divides and mitosis is complete

• The stage when DNA condenses into chromosomes

• The stage where chromosomes are pulled to opposite ends of the cell.

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

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 a difference between mitosis and meiosis? Mark ALL that apply!

• Mitosis occurs in the cytoplasm and Meiosis occurs in the nucleus.

• Mitosis results in diploid (2n) daughter cells and Meiosis results in haploid (n) daughter cells.

• Mitosis results in 2 daughter cells and Meiosis results in 4 daughter cells.

• Mitosis makes somatic (body) cells and Meiosis makes gametes (egg and sperm cells).
