Unit 8: Reproduction & Meiosis

Question 1

How do checkpoints in a cell cycle help make sure of accurate division?

Answer 1

Cell cycle checkpoints are surveillance mechanisms that monitor the order, integrity, and fidelity of the major events of the cell cycle. These include growth to the appropriate cell size, the replication and integrity of the chromosomes, and their accurate segregation at mitosis.

Question 2

What happens if the cell cycle is not properly regulated?

Answer 2

Disruption of normal regulation of the cell cycle can lead to diseases such as cancer. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor .

Question 3

What is the difference between Mitosis and Meiosis?

Answer 3

Mitosis is a type of cell division for somatic cells and for the asexual reproduction of unicellular eukaryotic cells. Meiosis is the type of cell division for the production of gametes in sexual reproduction.

Question 4

What type of daughter cell does meiosis produce?

Answer 4

4 Haploid Cells
