Name the four stages of cell division

G1,S,G2,M

1

Division of the nucleus

Karyokinesis

2

Division of the cytoplasm

Cytokinesis

3

Period between cell divisions when a cell metabolizes and prepares to divide

Interphase

4

What is part of interphase?

G1,S, G2

5

Connected by the centromere

Chromatids

6

Connects the chromatids

Centromere

7

Cell creates organelles and begins metabolism

G1

8

DNA synthesis in which the chromosomes of the cell are copied

S

9

Process that ensures that the normal number of chromosomes is restored after cell division

Synthesis (S phase)

10

Another name for mitosis

Karykinesis

11

body cell divides once to produce two daughter cells that are genetically identical to the parent cell

Mitosis

12

a sex cell divides twice to produce four genetically different daughter cells with one-half the number of chromosomes of a body cell.

Meiosis

13

How many chromosomes do body cells have?

46

14

How many chromosomes do sex cells have?

23

15

Made up of 2 chromatids connected by a centromere

Chromosome

16

The spot on the centromere where the spindle fiber attaches

Kinetechore

17

DNA is copied

Synthesis

18

Chromatin scrunches into chromosomes; centromere and spindle fibers appear to pull the chromosomes

Prophase

19

What disappears during prophase?

Nucleolus and nuclear membrane

20

Chromosomes line up in the middle of the cell

Metaphase

21

the chromatid arms separate and move to opposite ends of the cell

Anaphase

22

same size and the same shape and carry genes for the same traits but are NOT identical.

Homologous

23

The region near the nucleus where the centrioles are found that helps organize the spindle fibers during cell division

Centrosome

24

log-like structures that appear near the nucleus during cell division in an animal cell and move to opposite poles to pull the chromosomes apart.

Centrioles

25

Made of microtubules and connect each chromosome to the centrioles

Spindle fiber

26

The family of proteins that regulate the cell cycle in eukaryotic cells

Cyclins

27

When DNA and its attached proteins is spread out in the nucleus of non-dividing cells

Chromatin

28

When chromatin is scrunched up in dividing cells

Chromosomes

29

the process that a cell undergoes as it becomes specialized to perform very specific functions in the body.

Differentiation

30

Cell death

Apoptosis

31

Cell grows in preparation for cell division

G2

32

Cells are alive and metabolically active but do not divide; cannot be replaced when damaged

G0

33

Division of the cytoplasm

Cytokinesis

34

What is the product if a cell undergoes nuclear division but not cytoplasmic division

Binucleate
