6. The Cell Cycle and Mitosis

Question 1

What are the four phases of the cell cycle?

Answer 1

S phase
M phase
G1 phase
G2 Phase

Question 2

What is the S phase of the cell cycle?

Answer 2

synthesis phase; cell is actively replicating its genome

Question 3

What is the M phase of the cell cycle?

Answer 3

mitosis and cytokinesis occur

Question 4

What is mitosis?

Answer 4

partitioning of cellular components into two halves

Question 5

What is cytokinesis?

Answer 5

physical process of cell divsion

Question 6

What is interphase?

Answer 6

gap phases plus the S phase (G0)

Question 7

What are the four phases of mitosis?

Answer 7

prophase
metaphase
anaphase
telophase

Question 8

What occurs during prophase?

Answer 8

genome becomes visible once it condenses into densely packed chromosomes

Question 9

What occurs during metaphase?

Answer 9

chromosomes line up at the center of the cell forming the metaphase plate

Question 10

What occurs during anaphase?

Answer 10

spindle fibers short and the centromeres of each sister chromatid pair are pulled apart

Question 11

What occurs during telephase?

Answer 11

nuclear membrane forms around the bunch of chromosomes at each end of the cell

Question 12

What is a karyotype?

Answer 12

display of an organism’s genome
