Chapter 9b - Mitosis and Cytokinesis

Question 1

First stage of mitosis, during which the cell’s chromatin condenses into chromosomes

Answer 1

Prophase

Question 2

Structure that contains identical DNA copies and is formed during DNA replication

Answer 2

Sister CHromatid

Question 3

Cell structure that joins two sister chromatids

Answer 3

Centromere

Question 4

Structure made of spindle fibers, centrioles, and asterfiers that is involved in moving and organizing chromosomes before the cell divides

Answer 4

Spindle Apparatus

Question 5

Second stage of mitosis in which motor proteins pull sister chromatids to the cells equator

Answer 5

Metaphase

Question 6

Third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell

Answer 6

Anaphase

Question 7

Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided.

Answer 7

Telophase
