Question

model 1 - mitosis as part of the cell cycle
prophase
metaphase
anaphase
telophase
replicated chromosome (2 sister chromatids)
nuclear membrane
centriole
spindle fibers
nuclear division
mitosis
cytoplasmic division
cytokinesis

1. refer to model 1. list the four phases in the mitosis process.
2. where is mitosis in the cell cycle? before _____________ and after _____________
3. what three phases of the cell cycle are considered interphase?
4. refer to the cell cycle shown.

a. how many cells are present at the beginning of mitosis?
b. how many cells are present at the end of mitosis?

Explanation:

Step1: Identify mitosis phases from model

From the model, the four - phase names can be directly read.

Step2: Recall cell - cycle order

Mitosis occurs after interphase and before cytokinesis.

Step3: Recall interphase phases

Interphase consists of G1, S, and G2 phases.

Step4: Analyze cell numbers in mitosis

At the start of mitosis, there is 1 cell. At the end, after nuclear and cytoplasmic division, there are 2 cells.

Answer:

1. Prophase, Metaphase, Anaphase, Telophase
2. Cytokinesis; Interphase
3. G1 phase, S phase, G2 phase
4. a. 1

b. 2
