Mitosis

Question 1

Mitosis

Answer 1

Cell Replication and Division

Question 2

Stages of Mitosis

Answer 2

Interphase, Prophase, Prometaphase, Metaphase, Anaphase, and Telophase + Cytokinesis

Question 3

Interphase

Answer 3

A time when a cell produces a second set of identical DNA (S Phase) and uses gap phases to ensure quality control (G1/G2).

Question 4

Prophase

Answer 4

In this stage, the chromatin super-compresses into chromosomes, which are held together by centromeres. Centrosomes also begin to gravitate towards poles, while spindles also begin to form.

Question 5

Prometaphase

Answer 5

In this stage, the nuclear envelope breaks down and the centrosomes assume their positions at the poles. The centrosomes then form kinetochore microtubule spindles, which attach to chromosomes.

Question 6

Metaphase

Answer 6

In this stage, the chromosomes are lined up on the equatorial plate, where centromeres prepare to separate an equal number of chromosomes.

Question 7

Anaphase

Answer 7

In this stage, sister chromatids are split apart toward each pole of each respective centrosome, preparing for the cell to become two daughter cells.

Question 8

Telophase

Answer 8

In this stage, the cells begin to form separate nuclear envelopes.

Question 9

Cytokinesis

Answer 9

In this final stage, the two daughter cells physically separate by forming a cleavage furrow and then pinching themselves apart.
