Prophase
What is a key indicator of the prophase?
What is the condensation of a chromatin?
Microtubules enter nuclear area and some attach to ____________
What are kinetochores?
Centromeres are at _____ poles
Opposite
What happens to the sister chromatids, when the microtubules shorten?
They separate and move to opposite ends of the cell
What is the product of the telophase?
What are two daughter nuclei?
What structures begin to form from the centrosome during the prophase?
What is the mitotic spindle (microtubules)?
What breaks down during the prometaphase?
What is the nuclear envelope?
Where do the chromosomes line up at?
What is the metaphase plate?
What allows the sister chromatids to separate?
The break down of the protein "glue"
What happens to the chromosomes
They become less condensed
In prophase, what nuclear structure starts disappear?
What is the nucleoli?
What structural change happens to the chromosome as a result of it being further condensed?
The chromosomes become more compact as a result of it being condensed
What is the purpose of chromosomes aligning at the metaphase plate?
What is ensuring an equal distribution of genetic material to daughter cells?
What do the microtubules do?
They push poles apart?
The _______ is broken down into its building blocks
What is the mitotic spindle?
What begins to separate during the prophase?
What are centrosomes?
What area of DNA are the sister chromatids most tightly connected?
What are centromeres?
What happens if a chromosome is not properly aligned or attached?
The cell division will stop until the problem is fixed
What do kinetochore microtubules do?
They pull the chromosomes toward the poles
What appears as a result of the telophase?
What are nuclear membrane and nucleoli?
What do the duplicated chromosomes appear as?
What are the sister chromatids?
What structure forms when the microtubule extend from the centrosome towards the edge of cell?
What is an aster?
The ______ helps make sure that the sister chromatids will split up evenly between the daughter cells when they separate in the next step
spindle check point
What drives the processes in the anaphase?
How does cytokinesis in animals and plants differ?
In animals, a cleavage furrow will appear because a contractile ring of actin filaments. While in plants, the vesicles made by the Golgi will travel to the middle of the cell and form the cell plate.
