Prophase
Anatomy of a chromosome at the beginning of prophase
What are 2 sister chromatids and the centromere?
Fully formed in metaphase
What is mitotic spindle?
Shortest phase of mitosis
What is anaphase?
Marks the beginning of telophase
What is the stopping of chromosomal movement?
The last step in the cell cycle
What is cytokinesis?
Disappears during early prophase and can be more than one in the cell
What is nucleoli?
At opposite poles of the cell
What are centrosomes?
Chromatids become their own...
What are chromosomes?
Chromosomes works backwards and detangle to become...
What is chromatin?
Time period of cytokinesis
What is late anaphase and throughout telophase?
Breaks during late prophase
What is the nuclear envelope?
These are precisely aligned at the spindle equator
What are centromeres/chromosomes?
The v shaped thing being pulled towards opposite ends of the cell
What are daughter chromosomes?
Breaks down and disappears while nucleoli reappear w/in nuclei
What are spindles?
The end result of cytokinesis
What is two identical daughter cells?
Special protein structures at the centromere of each chromosome that microtubules latch onto and pull
What are kinetochores?
Trigger that separates chromatids from each other at the end of metaphase
What are enzymes?
The thing that pulls chromatids apart towards poles
What are kinetochore microtubules?
Newly formed around chromatin mass
What is a nuclear envelope?
The shell that divides
What is the cytoplasm?
The array of microtubules that extend from the centrosome matrix
What are asters?
The imaginary plane midway between the spindle poles
What is the metaphase plate?
The force that starts pushing the cell in two
What are nonkinetochore microtubules?
The cell has two nuclei
What is binucleate?
Forms the cleavage furrow and pinches cell apart
What is a contractile ring of actin microfilaments?
