M Phases Flashcards
What occurs in METOphase
Chromosomes line up across the cell
Microtubles connect the centromere to the two poles
What occurs in PROPHASE?
The longest phase
The chromosomes condense
The centrioles separate and go to each pole
Sprindles form
The nuclear membrane breaks down and nucleolus disappears
What occurs in ANOphase
Centromeres that join the sister chromatids split
The sister chromatids are pulled to the opposite sides of the cell
Why occurs in TELOphase?
Chromosomes begin to disperse
A nuclear membrane reforms
The splindle beings to break apart
The nucleolus reappears
During TElophase cytokinesis does what?
The cytoplasm bricked pinched and eventually the cell splits into two- cytokinesis
Chromosomes have segments called?
Genes
Chromatin condenses into?
Sister chromatins
Sister chromatids are connected by?
Centremere
Centromeres split apart by?
Centrioles
Centrioles are attached by webloke thread called?
Spindle fibers
