Cell Cycle

Question 0

What are the functions of mitosis?

Answer 0

1. Asexual reproduction (in unicellular organisms)

2. Growth, repair, and development of an organism (multicellular organisms)

Question 1

What is the product of cell division (mitosis)?

Answer 1

a genetically identical copy of itself

Question 2

What are the two major phases of cell division?

Answer 2

1. Interphase

2. M phase (cell division)

Question 3

What does a parent cell divide into?

Answer 3

2 daughter cells

Question 4

Interphase takes how much of a cell’s life.

Answer 4

90%

Question 5

What are the three stages of interphase?

Answer 5

G1 Phase, S Phase, and G2 Phase

Question 6

What happens during G1 phase?

Answer 6

Cell growth and copying of organelles

Question 7

What happens during S Phase?

Answer 7

Synthesis of DNA and replication of chromosomes

Question 8

What happens during G2 Phase?

Answer 8

Preparation for mitosis (organelles required for mitosis produced

Question 9

What are the two stages of M Phase?

Answer 9

Mitosis and cytokinesis

Question 10

What are the four steps of mitosis?

Answer 10

Prophase, Metaphase, Anaphase, and Telophase

Question 11

What is mitosis?

Answer 11

Division of the nucleus

Question 12

What is cytokinesis?

Answer 12

Division of cytoplasm and organelles between two cells

Question 13

What happens during prophase?

Answer 13

Chromatin organizes into chromosomes (sister chromatids) and nuclear membrane disappears

Question 14

What happens during metaphase?

Answer 14

sister chromatids line up at the cell’s equator and spindle fibers appear and attach to the centromere

Question 15

What happens during anaphase?

Answer 15

Spindle fibers shorten, pulling the sister chromatids apart toward each new cell

Question 16

What happens during telophase?

Answer 16

The nucleus reappears in both cells and chromosomes decondense into chromatin

Question 17

What is the difference in cytokinesis between plant and animal cells

Answer 17

Animal cells develop a cleavage furrow that pinches in and plant cells build a wall separates the two new cells

Question 18

What is the acronym for cell division

Answer 18

I.P.MAT

Question 19

What are regulatory proteins/cydin?

Answer 19

Control cell division

Question 20

What is apoptosis and what is its function?

Answer 20

Programmed cell death and is the key to developing tissues and organs
