Module 4 - Mitosis

Question 1

Reasons of Cellular Reproduction

Answer 1

(1) Growth
(2) Ensure genome persistence
(3) Repair

Question 2

Original Cell is ____ and the product cells are called ___

Answer 2

Parent cell ; Daughter cells

Question 3

Two types of cells:

Answer 3

Prokaryotic (single celled organisms) and Eukaryotic cells (animal and plant cells)

Question 4

(1) Chromosome replicates into identical loops and attaches to the opposite sides of plasma membrane
(2) Membrane grows and cytoplasm divides creating two new cells

Answer 4

Binary Fission, happens in prokaryotic cells

Question 5

Eukaryotic cells divide through a series of growth through

Answer 5

Cell Cycle

1) Interphase (90% of the process
(2) Division Phase

Question 6

Interphase Stages

Answer 6

G1 (Cell growth)
S (DNA Replication)
G2 (Preparation for Mitosis, doubling of organelles; prep of centrioles)

Question 7

Division Phase Process

Answer 7

(1) Mitosis
- Prophase
- Metaphase
- Anaphase
- Telophase

(2)Cytokinesis

Question 8

Process that divides the cell nucleus to produce new nuclei with a complete set of chromosomes

Answer 8

Mitosis

Question 9

• Chromosomes are visible (sister chromatids)
• Centrioles slowly migrate to the poles
• Nuclear membrane disappears
• Spindle fiber forms

Answer 9

Prophase

Question 10

• Chromosomes line up on the equator of the cell

- Spindles attach to centromeres (center of chromosomes)

Answer 10

Metaphase

Question 11

• Sister chromatids separate
• Centromeres divide
• Sister chromatids move to opposite poles

Answer 11

Anaphase

Question 12

• Chromosomes uncoil (Chromatin)
• Nuclear membrane reforms
• Spindle dissapears

Answer 12

Telophase

Question 13

Occurs at the end of mitosis

• Organelles are divided
• Cytoplasm divides

Daughter cells are genetically identical

Answer 13

Cytokinesis
