phases of mitosis

What is the first stage of mitosis

Prophase

What is the second step of mitosis

Prometaphase

What is the third phase of mitosis

Metaphase

What is the 4th phase of mitosis

Anaphase

What is the 5th step

Telophase

What is the following step of telophase

Cytokineses

What is the end product of mitosis

Two identical daughter cells contains all genetic information pertains to that organism

What is occurring in G2

Cell growth continues and there is synthesis of special proteins in preparation for mitosis

What happens to the chromatin during prophase

Becomes tightly coiled (condensed) forms the common shape with sister chromatids

What’s links two sister chromatids

A centromere

What does the mitotic spindle do

Divides chromosomes

What is the mitosis spindle composed of

Microtubles that are produced by centrosomes structured in the cytoplasm

What happened during interphase (before mitosis beings)

Duplication of the chromosomes (DNA)

During what stage does the nucleus disassemble

Metaphase

Chromosomes line up in the middle is what stage

The stage is metaphase

What are the pulls called pulling the sister chromatids apart during anaphase

Spindle fibers (microtubules) kenticochores

What stage causes the sister chromatids to be separated to the edges of the cell

Anaphase

What stage has the location of the sister chromosomes on complete opposite sides the of the cell

Telephase is the stage

During what stage is the reformation fo two nuclei on both sides of the cell

Telephase

What stage is responsible for the final separation of the two cells by splitting the cytoplasm

Cytokinesis

Where do the spindal fibers (kinetochores) connect to the chromosomes during metaphase

The centromeres (which is the DNA sequence)

Telephase does what to the chromosomes shape

They become lose again like noodles

The formation of a contracting ring of micro filaments interacting with myosin that deepen into cells to separate the contents into two separate cells is called what

Cleavage furrow

During what phase does the mitotic spindle begin to form and create two poles of the spindal apparatus (but does not attach to the chromosomes)

Prophase

The line in the middle of the cell where the chromosomes line up during metaphase is referred to as what

The equatorial plane or metaphase plate

Unlike animal cells plant cells have cell walls how do their cells separate during cytokinins

Formation of a cell plate

Chromosomes after DNA replication consist of what

Two sister chromatids connected by a centromere

These attach to the plasma membrane and are apart of the centrioles during metaphase

Asters

These are large protein structures assembled on the centromere of each sister chromatid they are the attachment point for micrtubles of the mitotic spindle

Kinetochore

What occurs during s phase in the cell cycle

Cellular DNA is replicated and the two daughter cells each get one set of DNA
