Cell Division Quiz

You are not genetically identical to your parents or siblings (if you have any). How does this genetic diversity occur. Explain the two processes and discuss why it matter to the success of our species.

Describe the role of cyclins and cyclin-dependent kinases (CDKs) in cell cycle regulation.

• They form the spindle fibers during mitosis.

• They are involved in the synthesis of DNA.

• They regulate the progression of cells through the cell cycle.

• They are responsible for cytokinesis.

Janet Jackson is a 50 year old women, who recently found out she was pregnant. Why was it suggested that she have genetic testing done? What are they concerned occurred and why could this be harmful to the fetus?

Many people are concerned with the process of aging. In some research we reviewed, explain what chromosome part maybe responsible for this aging and why does it occur?

Evaluate the impact of mutations in genes that regulate the cell cycle on cancer development.

What is the role of cyclins and cyclin-dependent kinases (CDKs) in the cell cycle?

• They degrade cellular components necessary for cell division.

• They act as structural components of the cell membrane.

• They are involved in the replication of DNA.

• They regulate the cell cycle through phosphorylation of proteins.

In cell cycle regulation one protein is considered the brake the other is the accelarator. Identify theses proteins, connect them to their proper analogy and explain how they function like the brake or the accelarator.

Cancer is not just one disease but many different diseases that cause the same issue. Explain what that issue is, what are some reason it occurs, and why cancer cells are so disruptive to our bodies. Use the phases of the cell cycle to explain what normally should be ocurring in the life cycle of a cell and what happens to the cycle when the cell becomes cancerous.
