Chapter 10- Cell Division

Question 1 - 10 • This is the process by which a cell divides into 2 daughter cells.

Answer 1 – 10 • What is cell division?

Question 1 - 20 • Collectively, this part of the cell cycle includes the G1, S and G2 phases. They are the “intermediate” phases between periods of cell division.

Answer 1 – 20 • What is interphase?

Question 1 - 30 • When chromosomes replicate, they form these. It looks like an “x” shape.

Answer 1 – 30 • What are sister chromatids?

Question 1 - 40 • This is the area where sister chromatids attach. When the spindle forms, this is the part of the sister chromatids that binds to the spindle.

Answer 1 – 40 • What is the centromere?

Question 1 - 50 • This is a protein that regulates the timing of the cell cycle.

Answer 1 – 50 • What is a cyclin?

Question 2 - 10 • The cell cycle consists of this many phases?

Answer 2 – 10 • What are four?

Question 2 - 20 • Cell division occurs in the M phase of the cell cycle. It is made up of these two parts?

Answer 2 – 20 • What are mitosis and cytokinesis?

Question 2 - 30 • These two phases of the cell cycle control the growth of cells, in between periods of division.

Answer 2 – 30 • What are the G1 ad G2 phases?

Question 2 - 40 • These are the phases of the cell cycle, in order.

Answer 2 – 40 • What are M, G1, S and G2?

Question 2 - 50 • Chromosome replication occurs during this phase of the cell cycle.

Answer 2 – 50 • What is the S phase?

Question 3 - 10 • Mitosis is the division of the nucleus. This is the division of the cytoplasm.

Answer 3 – 10 • What is cytokinesis?

Question 3 - 20 • Mitosis occurs during this phase of the cell cycle.

Answer 3 – 20 • What is M phase?

Question 3 - 30 • This is the longest phase of mitosis. Chromosomes condense, the nuclear envelope disappears and the centrioles form a spindle across the cell.

Answer 3 – 30 • What is prophase?

Question 3 - 40 • During this phase, the sister chromatids split, becoming two individual chromosomes. They begin to move to opposite ends of the cell.

Answer 3 – 40 • What is anaphase?

Question 3 - 50 • Cytokinesis usually happens at the same time as this phase of mitosis

Answer 3 – 50 • What is telophase?

Question 4 - 10 • Cytokinesis is the division of the cytoplasm. This is the division of the nucleus.

Answer 4 – 10 • What is mitosis?

Question 4 - 20 • This is the acronym for the four phases of mitosis.

Answer 4 – 20 • What is PMAT?

Question 4 - 30 • During this phase, the sister chromatids line up across the center of the cell and their centromeres attach to the spindle.

Answer 4 – 30 • What is metaphase?

Question 4 - 40 • During this phase, the spindle disappears nuclear envelopes re-form around the two new sets of chromosomes.

Answer 4 – 40 • What is telophase?

Question 4 - 50 • During cytokinesis, animal cell membranes simply draw in and pinch off, creating two new cells. However, in plant cells, this structure forms as a precursor to the cell wall.

Answer 4 – 50 • What is the cell plate?

Question 5 - 10 • Uncontrolled cell growth can cause this disease?

Answer 5 – 10 • What is cancer?

Question 5 - 20 • This is a form of cancer treatment where toxic chemicals are used to alter the cell cycle of cancerous cells.

Answer 5 – 20 • What is chemotherapy?

Question 5 - 30 • There are two types of cyclin drugs. Internal regulators respond to events inside the cell while these respond to signals outside the cell.

Answer 5 – 30 • What are external regulators?

Question 5 - 40 • When functioning properly, this gene is in charge of pausing cell division until all DNA is properly copied.

Answer 5 – 40 • What is the p53 gene?
