Cell Divison

Question 1

Cell Division

Answer 1

essential process where new cells are reproduced from old ones, chromosome is needed

Question 2

2 CD Processes of Eukaryotes

Answer 2

karyokinesis (nuclear division) or genetic material distribution and cytokinesis (cytoplasmic division) separation of cell

Question 3

Cell Cycle

Answer 3

sequence of stages, 3 continuous stages (interphase, mitosis, and cytokinesis)

Question 4

Interphase

Answer 4

period before mitosis or preparatory phase, longest 90%

Question 5

G1 Phase

Answer 5

synthesized DNA, RNA, and protein (duplicated chromosomes)

Question 6

S Phase

Answer 6

synthesis, duplicated DNA, 2 chromatid

Question 7

G2 Phase

Answer 7

duplicated centrosome, cell increases size, prevents errors

Question 8

Mitosis

Answer 8

2 identical cell results, formula N(2), main target is repair, regeneration, and growth

Question 9

Mitotic Cell

Answer 9

has an ability to multiply, ex. blood cell

Question 10

Amitotic Cell

Answer 10

cannot be replenished, ex. nerve cell

Question 11

Prophase

Answer 11

chromosome gets bigger and scatters

Question 12

Metaphase

Answer 12

chromosome line up

Question 13

Anaphase

Answer 13

2 chromatids

Question 14

Telophase

Answer 14

2 genetically identical cell

Question 15

Cleavage Furrow

Answer 15

for animals

Question 16

Cell Plate

Answer 16

for plants

Question 17

Cytokinesis

Answer 17

splitting of cell or cytoplasm

Question 18

Meiosis

Answer 18

result is 4 haploids, formula N(4)

Question 19

Prophase 1

Answer 19

longest 90%, 5 substages

Question 20

Bivalent (Tetrad)

Answer 20

from synapsis or pairing up of homologous chromosomes

Question 21

Crossing Over

Answer 21

exchange of genetic materials at chiasmata

Question 22

Leptolene

Answer 22

visible chromosome

Question 23

Zygotene

Answer 23

start to pair up homologous chromosome

Question 24

Pachytene

Answer 24

synapsis and crossing over takes place

Question 25

Diplotene

Answer 25

4 chromatids of tetrad repel each other

Question 26

Diakinesis

Answer 26

condense further homologous chromosomes

Question 27

Metaphase I

Answer 27

bivalent align

Question 28

Anaphase I

Answer 28

separate bivalent

Question 29

Telophase I

Answer 29

duplicated chromosome, complete haploid set

Question 30

Interkinesis or Interphase II

Answer 30

only in animal cells, no DNA replication

Question 31

Prophase II

Answer 31

centrosome move toward poles

Question 32

Metaphase II

Answer 32

align chromosome

Question 33

Anaphase II

Answer 33

centrosome separate

Question 34

Telophase II

Answer 34

chromosome condense

Question 35

Cytokinesis

Answer 35

separate cell and produce 4 haploid cells
