Cell divisionReview
This spot that holds the 2 chromatid copies together is called a ______________________
centromere
Cell division in bacteria cells is called
_______________________ Binary fission
Phase of the cell cycle in whichDNA is copied
S (synthesis)
Phase of the cell cyclein which the nuclear membrane is presentand DNA is spread out into chromatin. interphase
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
Phase of mitosis that followsanaphase
telophase
Phase of the cell cycle that follows G2
Mitosis (prophase)
This network of fibersthat attach and pullthe chromosomesapart is called the
mitotic ______________spindle
This cell is in__________________prophase
G1, S, and G2 make up this phaseof the cell cycle.
interphase
Plant cells can’t pinch to divide, instead they form a _______________to divide.
cell plate
This phase of thecell cycle is______________anaphase
Part of interphase in which thecell grows to mature size and carries out its job. G1
Phase of mitosis that followsprophase
metaphase
Phase of the cell cycle that follows S
G2
This phase of the
cell cycle is
________________metaphase
Phase of the cell cycle cell’s spendmost of their time in.
G1 of interphase
Disorder in which body cells lose their ability to control cell division
cancer
One of 2 identical armsthat make up a chromosome
chromatid
DNA that is all spread out inan interphase nucleus is called________________chromatin
Phase of mitosis in which thenuclear membrane and nucleolusdisappear and the DNA scrunches into chromosomes.
prophase
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
These structuresat the poles whichattach to the spindle fibers and pull the chromosomes.
centrioles
The cell above is in ______phase meta
When chromatin scrunches together it is called a _________________chromosome
One of 2 identical armsthat make up a chromosome
chromatid
Phase of mitosis that followsmetaphase
anaphase
Phase of the cell cycle that follows G1
S
This cell is in___________anaphase
Phase of cell division in whichthe nuclear membrane returns andchromosomes spread out into chromatin. telophase
This cell is in__________telophase
The cell above is a _________ cell.
animal plant
PlantYou can see the cell plate forming in center insteadof a cleavage furrow.
Phase of the cell cycle after S phasein which cells make the moleculesand organelles needed for cell division
G2
Phase of mitosis in which chromatids separate and move to oppositeends of the cell.
anaphase
The very first dividing phase is_______________prophase
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
This is called a ______________Cleavage furrow
This cell is _____________ cell.
an animal a plant
an animalPlants don’t have cleavage furrows.
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
________________ 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
INTERPHASE
PROPHASE
INTERPHASE
METAPHASE
Prophase (P) Metaphase (M) Anaphase (A) Telophase (T)
Interphase (I)
_______________ 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
INTERPHASE
ANAPHASE
TELOPHASE
PROPHASE
Prophase (P) Metaphase (M) Anaphase (A) Telophase (T)Interphase (I)
__________________ 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
