Chapter 10: 10.2 Mitosis

Question 1

Mitosis

Answer 1

Known as M Phase
* Part of cell cycle in which a cell divides into two identical daughter cells
* Genetically identical to each other and the mother cell

Question 2

What phases can the M phase of the cell be divided into?

Answer 2

• Mitosis
• Cytokinesis

Question 3

What is mitosis also known as?

Answer 3

Karyokinesis
* Division of the nuclear contents

Question 4

What is cytokinesis?

Answer 4

Separation of the cytoplasmic components into two daughter cells

Question 5

True or False:

Most of the cell division in our bodies occurs through meiosis

Answer 5

False, most of the cell division in our bodies occurs through mitosis

Question 6

Mitosis is for…

Answer 6

• Growth
• Replace old and dying cells

Question 7

Question 8

What is the metaphse plate also sometimes known as?

Answer 8

Equatorial plane

Question 9

In metaphase, are the chromatids attached to each other?

Answer 9

Yes, but they are in maximal condensation

Question 10

What happens to the microtubules in anaphase that are not attached to chromosomes?

Answer 10

Push apart, causes the cell to elongate and the poles to move away from each other

Question 11

In telophase, what does the mitotic spindle break down into?

Answer 11

Tubulin monomers
* Forms the cytoskeleton of the daughter cells

Question 12

True or False:

Chromosomes decondense in the telophase

Answer 12

True, they START to decondense

Question 13

What else starts to form during telophase?

Answer 13

Nuclear envelope
