mitosis

Question 1

Mitosis

Answer 1

cellular division in which the daughter cells receive the exact chromosomes and genetic make up of the parent cell

Question 2

Phases in mitosis

Answer 2

prophase, metaphase, anaphase, telophase

Question 3

Importance of mitosis

Answer 3

• provides new cells for growth
• replaces worn-out cells
• single-celled organisms rely on mitosis as their primary means of asexual reproduction

Question 4

Chromosomes in prophase

Answer 4

remain visible

Question 5

Chromosomes in metaphase

Answer 5

move to the equator of the spindle

Question 6

Chromosomes in anaphase

Answer 6

are pulled toward opposite poles

Question 7

Chromosomes in telophase

Answer 7

arrive at the opposite poles

Question 8

Number of chromatids in prophase

Answer 8

1 chromosome = 2 chromatid

Question 9

Number of chromatids in metaphase

Answer 9

1=2

Question 10

Number of chromatids in anaphase

Answer 10

1=1

Question 11

Number of chromatids in telophase

Answer 11

1=1

Question 12

Cell cycle

Answer 12

sequence of growth and division of a cell

Question 13

Phases of cell cycles

Answer 13

• interphase (G1, S, G2)
• mitosis
• cytokinesis

Question 14

Functions of mitosis

Answer 14

• increase the number of cells
• create new cells
• play an important role in asexual reproduction of single-celled organism
• guarantees genetic continuity

Question 15

Functions of cell cycle

Answer 15

• help cell’s growth and division
• separate the two daughter cells
• duplicate the DNA in chromosomes for the two daughter cells
