MITOSIS

Question 1

interphase

Answer 1

period between 2 mitotic divisions, cell grows, copies DNA, and synthesizes proteins

Question 2

prophase

Answer 2

first stage of mitosis in cell division
condensation of chromosomes and dissolution of nuclear envelope
chromosomes (DNA) replicates

Question 3

metaphase

Answer 3

all of the chromosomes move to the cell’s equator

Question 4

anaphase

Answer 4

chromosomes separate

* mitotic spindle pulls sister chromatids to opposite poles

Question 5

telaphase

Answer 5

final stage of mitosis

nuclear membrane forms around each set of new chromosomes, cell division begins, mitotic spindles disappear

Question 6

cytokinesis

Answer 6

division of the cytoplasma of a cell, follows the division of the cells nucleus
*Cell divides, two daughter cells form

Question 7

Prometaphase

Answer 7

nucleus dissolves, mitotic spindle (microtubules) attach to centromeres

Question 8

chromosome

Answer 8

eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein in a prokaryotic cell-main ring of DNA

Question 9

chromatid

Answer 9

one of the 2 stands of a chromosome that become visible during mitosis

Question 10

centromere

Answer 10

region of chromosomes that hold the 2 sister chromatids together during mitosis

Question 11

Cell cycle

Answer 11

repeating sets of events in a life of a cell

Question 12

mitosis

Answer 12

eukaryotic cell, process of cell division that forms 2 new nuclei each of which has the same number of chromosomes

Question 13

cancer

Answer 13

a tumor where the cells begin dividing at an uncontrolled rate and become invasive

Question 14

centriole

Answer 14

organelle that is composed of 2 short microtubules at right angles to each other and have an active role in mitosis

Question 15

cell plate

Answer 15

precursor of a new plant cell wall that forms during cell division and divides a cell into 2

Question 16

spindle fiber

Answer 16

one of the microtubules that extend across a dividing eukaryotic cell
assists in the movement of chromosomes

Question 17

nucleus

Answer 17

eukaryotic cell membrane bound organelle that contains the cells DNA and has a role in processes like metabolism, growth, and reproduction

Question 18

what is the relationship betwenn interphase and cytokinesis

Answer 18

interphase is not cell division and cytokinesis is cell division

Question 19

is interphase a part of mitosis?

Answer 19

NO

Question 20

what happens after cytokinesis?

Answer 20

interphase starts again

Question 21

when is chromatin present?

Answer 21

interphase

Question 22

when are chromosomes present ?

Answer 22

prophase and metaphase

Question 23

when are chromatids present?

Answer 23

anaphase

Question 24

G1

Answer 24

Cell grows and carry a out regular cell functions

Organelles reproduce

Question 25

S

Answer 25

Cell replicates DNA resulting in duplicated chromosomes

Question 26

G2

Answer 26

Cell continues to grow and prepare for cell division critical checkpoint Fixed -> mitosis

Question 27

How many chromosomes are totaled in body cells ?

Answer 27

46

Question 28

Chromatin appear and 2 centrioles

Answer 28

Interphase

Question 29

Centrioles duplicate & nuclear envelope breaks down

Answer 29

Prophase

Question 30

Spindle fibers attach to centromeres

Answer 30

Metaphase

Question 31

Pull info to each side

Answer 31

Anaphase

Question 32

Nuclear envelope reforms to contain genetic information

Answer 32

Telophase

Question 33

Two cells, chromosomes->chromatin

Answer 33

Cytokinesis

Question 34

Telophase what forms that is different in animal and plant cells ?

Answer 34

Animal cells=cleavage furrow | Plant cells=cell plate

Question 35

Binary fission

Answer 35

Method where bacteria reproduce | DNA molecule is replicated; cell splits in 2 identical cells each containing an exact copy of DNA

Question 36

How does binary fission work ?

Answer 36

Single DNA molecule replicates and then the DNA strands separate -> cross wall formation = 2 daughter cells of identical composition

Question 37

Characteristics prokaryote cells have the eukaryotic don't

Answer 37

No nucleus Unicellular only No membrane bound organelles

Question 38

2 reasons for cell division

Answer 38

Cell growth & repair

Question 39

4 stages of mitosis

Answer 39

Prophase Metaphase Anaphase Telophase
