During which stage of mitosis do chromosomes first become visible as distinct structures?
Prophase
During the Prometaphase what happens to the nuclear envelope?
It start to breakdown so spindle fibers can reach the chromosomes.
The imaginary line where chromosomes align during metaphase is called this.
Metaphase Plate
Anaphase ensures that each new cell will get the correct number of?
Chromosomes
In this stage of mitosis, the chromosomes begin to uncoil and two new nuclear envelopes form.
Telophase
In prophase, these threadlike structures condense into thick, visible chromosomes.
Chromatin
What cell structure attach to the chromosomes in the Prometaphase?
Microtubules attach to Kinetochores.
During this mitosis stage, chromosomes line up across the middle of the cell.
Metaphase
The protein structures that shorten to pull the chromatids apart.
Microtublues
The process that splits the cytoplasm into two separate daughter cells is called this.
Cytokinesis
During prophase, the nuclear envelope begins to do this.
Break down or Disassemble
Where is the Kinetohchores located?
In the Chromosome
Metaphase follows this stage of mitosis
Prometaphase
The phase of mitosis where sister chromatids separate and move to opposite sides of the cell.
Anaphase
During telophase in animal cells, this structure reappears around each set of chromosomes.
Nuclear Envelope
These cell structures begin moving to opposite poles to help form the mitotic spindle.
Centrosomes
Why is prometaphase important for mitosis?
It makes sure each chromatid attaches to spindle fibers from opposite poles.
During metaphase, each duplicated chromosome is made of these two identical parts joined at the centromere.
Sister Chromatids
The two separated chromatids move toward these areas of the cell during anaphase.
Opposite ends of the cell
In plant cells, cytokinesis happens when this new structure forms between the two nuclei.
Cell plate
The protein fibers that attach to chromosomes and help pull them apart start forming during prophase.
Miotic Spindle
What is the difference between prophase and prometaphase?
In prophase the nuclear envelope is still intact, while in prometaphase it has disassembled and microtubules attach to chromosomes.
The protein structures on the centromeres of chromosomes that spindle fibers attach to.
Kinetochores
Anaphase is part of this larger process that produces two identical daughter cells?
Mitosis
In animal cells, cytokinesis occurs when the cell membrane pinches inward, forming this.
