Mitosis and Meiosis

Question 1

processes of cell division

Answer 1

mitosis and meiosis

Question 2

what does mitosis produce?

Answer 2

new daughter cells that contain the same number and composition of chromosomes as the original (parent) cell

Question 3

what is mitosis used for?

Answer 3

it is used by the body for growth and repair. it is used by simple animals for asexual reproduction

Question 4

cell cycle

Answer 4

the entire life of a cell, from its birth to its death

Question 5

two major phases of the cell cycle

Answer 5

interphase and cell division

Question 6

interphase

Answer 6

the cell grows in size, genetic material is synthesized, and the cell performs its normal bodily function

Question 7

interphase subphases

Answer 7

G1 phase, S phase, G2 phase

Question 8

G1 phase

Answer 8

a period of rapid cell growth and the formation of cellular organelles

Question 9

S phase

Answer 9

where the genetic material of the cell gets duplicated into sister chromatids

Question 10

G2 phase

Answer 10

cell prepares itself for cellular division by producing extra cellular organelles and the proteins necessary for cell division

Question 11

cell division phase

Answer 11

either mitosis or meiosis occurs and accounts for only about 5-10% of the cell cycle

Question 12

subphases of the cell division phase

Answer 12

nuclear division and cytokinesis

Question 13

stages of mitosis

Answer 13

prophase, metaphase, anaphase, telophase

Question 14

prophase

Answer 14

-longest
-DNA coils around proteins into sister chromatids
-nuclear envelope broken down
-centrioles form spindle fibers

Question 15

metaphase

Answer 15

-sister chromatids align along the center of the cell

Question 16

anaphase

Answer 16

centrioles and spindles pull the sister chromatids apart from one another and towards the opposite ends of the cell

Question 17

telophase

Answer 17

reverses everything that happened in prophase, creating a single cell with two separate nuclei and DNA

Question 18

when does crossing over occur?

Answer 18

prophase 1

Question 19

which stage are two nuclei formed?

Answer 19

interphase

Question 20

which stage do the chromosomes line up along the equator?

Answer 20

metaphase

Question 21

which stage do the spindles form?

Answer 21

prophase

Question 22

which stage separates the sister chromatids?

Answer 22

anaphase

Question 23

which stage are daughter cells formed?

Answer 23

interphase

Question 24

which stage reforms the nuclei?

Answer 24

telophase

Question 25

which stage are the chromosomes first seen?

Answer 25

prophase

Question 26

which division has sister chromatids?

Answer 26

prophase 2??

Question 27

which division has homologous chromosomes?

Answer 27

prophase 1

Question 28

which stage has tetrads?

Answer 28

prophase 1

Question 29

which stage separates the sister chromatids?

Answer 29

anaphase 2

Question 30

which stage separates the homologous chromosomes?

Answer 30

anaphase 1

Question 31

which stage reforms the nuclei?

Answer 31

telophase

Question 32

what occurs in the G1 phase of the cell cycle?

Answer 32

cell growth and normal cell functions

Question 33

cytokinesis in animal cells starts by forming a

Answer 33

cleavage furrow
