slide2
This spot that holds the 2 chromatid copies together is called a ______________________

centromere

The phase of the cell cycle

in which cells stop dividing all together.

G0

slide3

Binary fission

Cell division in bacteria cells is called

_______________________

Phase of the cell cycle in which

DNA is copied

S (synthesis)

slide4

cyclins

The proteins that control the cell cycle

Phase of the cell cycle

in which the nuclear membrane is presentand DNA is spread out into chromatin.

interphase

slide5
Type of cell division in eukaryoticcells that results in 2 identical daughter cells.

mitosis

List the phases of mitosis in orderstarting with prophase.

Prophase, metaphase, anaphase, telophase, cytokinesis

slide6

telophase

Phase of mitosis that followsanaphase

Phase of the cell cycle that follows G2

Mitosis (prophase)

slide7
This network of fibersthat attach and pullthe chromosomesapart is called the

mitotic ______________

spindle

This cell is in__________________

prophase

slide8
G1, S, and G2 make up this phaseof the cell cycle.

interphase

Area near the nucleus that contains the centrioles and helps to organize spindle formation ______________

centrosome

slide9
The place in the cell membrane of an animal cell that pinches in during cytokinesis is called a

____________________

cleavage furrow

Plant cells can’t pinch to divide, instead they form a _______________

to divide.

cell plate

slide10

anaphase

This phase of thecell cycle is______________

Part of interphase in which thecell grows to mature size and carries

out its job.

G1

slide11

metaphase

Phase of mitosis that followsprophase

Phase of the cell cycle that follows S

G2

slide12

metaphase

This phase of the

cell cycle is

________________

Phase of the cell cycle cell’s spend

most of their time in.

G1 of interphase

slide13
Disorder in which body cells lose their ability to control cell division

cancer

One of 2 identical armsthat make up a chromosome

chromatid

slide14

chromatin

DNA that is all spread out inan interphase nucleus is called________________

Phase of mitosis in which thenuclear membrane and nucleolusdisappear and the DNA scrunches into chromosomes.

prophase

slide15
In this part of interphase cellsmake the molecules and organellesneeded for cell division

G2

The 2 copies of each chromosomeare called ______________ chromosomes because are the same size,

same shape, and carry genes for thesame traits.

homologous

slide16
These structuresat the poles whichattach to the spindle fibers and pull the chromosomes.

centrioles

The cell above is in ______phase

meta

slide17

chromosome

When chromatin scrunches together it is called a _________________

One of 2 identical armsthat make up a chromosome

chromatid

slide18

anaphase

Phase of mitosis that followsmetaphase

Phase of the cell cycle that follows G1

S

slide19

anaphase

This cell is in___________

Phase of cell division in whichthe nuclear membrane returns andchromosomes spread out into chromatin.

telophase

slide20

telophase

This cell is in__________

The cell above is a _________ cell.

animal plant

Plant

You can see the cell plate forming in center insteadof a cleavage furrow.

slide21

carcinogen

Substance that causes cancer

Phase of the cell cycle after S phasein which cells make the moleculesand organelles needed for cell division

G2

slide22
Phase of mitosis in which chromatids separate and move to oppositeends of the cell.

anaphase

The very first dividing phase is_______________

prophase

slide23
Phase of the cell cycle where cells spend most of their time. They grow bigger and they do their jobas body cells.

G1

List the phases of mitosis in orderstarting with interphase

Interphase, prophase, metaphase, anaphase, telophase, cytokinesis

slide24

Cleavage furrow

This is called a ______________

This cell is _____________ cell.

an animal a plant

an animalPlants don’t have cleavage furrows.

slide25
Condition in which a cell grows too big for its DNA to handle the demand for information

DNA overload

slide26
Phase of mitosis where the cytoplasm splits into 2

CYTOKINESIS

Name the phases of the cell cycle in order starting with G1

G1 S G2 M C

slide27

Prophase (P) Metaphase (M) Anaphase (A) Telophase (T)

Interphase (I)

INTERPHASE

________________ DNA is all spread out as chromatin and nuclear membrane is visible

________________ DNA scrunches up and chromosomes are first visible

________________ Made up of G1, S, G2

________________ Chromosomes line up in middle of cell

PROPHASE

INTERPHASE

METAPHASE

slide28

Prophase (P) Metaphase (M) Anaphase (A) Telophase (T)

Interphase (I)

INTERPHASE

_______________ DNA is copied and cell prepares to divide

_______________ Chromatid arms separate and move to opposite ends of the cell

_______________ Chromosomes unwind into chromatin & nucleus returns

_______________ Nuclear membrane & nucleolus disappear

ANAPHASE

TELOPHASE

PROPHASE

slide29

Prophase (P) Metaphase (M) Anaphase (A) Telophase (T)

Interphase (I)

TELOPHASE

__________________ Two nuclei are visible

__________________ First dividing phase

___________________ Centrosomes containing centrioles & spindle fibers appear next to nucleus

__________________Cytoplasm is split between two cells

_________________ Spindle fibers and centrioles disappear

PROPHASE
