Prophase
Spindle fibers emerge from this structure.
What is centrosome?
____ are the center point of chromosomes.
What is centromeres?
This is how sister chromatids split.
What is spindle fibers shorten?
Telophase prepares for this step.
What is cytokinesis?
In animal cells, this structure separates the daughter cells during cytokinesis.
What is a cleavage furrow?
This structure disappears during prophase.
What is the nucleolus?
Spindles connect to _____.
Kinetochores
In anaphase, sister chromatids are now called ____.
What is chromosomes?
This structure pushes poles apart.
What is spindle fibers?
In plant cells, this structure, the precursor to a new cell wall, separates the daughter cells during cytokinesis.
What is a cell plate?
These two organelles are disperse during prophase.
What is the Golgi apparatus and the endoplasmic reticulum?
Each sister chromatid is attached to a spindle fiber originating from _____.
What is opposite poles?
These cellular structures elongate during anaphase.
What is spindle fibers?
Chromosomes arrive at these locations and begin to decondense during telophase.
What is opposite poles?
A cell can end up with multiple nuclei within a single cytoplasm and an abnormal number of chromosomes, which can lead to genetic disorders.
What is the consequence of cytokinesis failure?
This cellular structure breaks down during prophase.
What is the nuclear envelope?
This checkpoint ensures chromosomes are properly aligned before proceeding.
What is the spindle checkpoint?
After anaphase occurs, sister chromatids which are now called chromosomes and are pulled toward ______ poles.
What is opposite?
The material that surrounds each set of chromosomes during telophase.
What is nuclear envelope material?
The key stages of cytokinesis in animal cells.
What is initiation, contraction, and membrane scission?
______ condense and become visible during prophase.
What is chromosomes?
Chromosomes are lined up at this location during metaphase.
What is the metaphase plate?
These cellular structures split in two during anaphase.
What is centromeres?
The structure that breaks down and disappears during telophase as the chromosomes reach the opposite poles of the cell. (hint: the kinetochores attach to this structure during prophase)
What is the mitotic spindle?
_____ is the failure of chromosomes to separate properly during cell division, resulting in an abnormal amount of chromosomes in the daughter cells. The cell either has too many or too few chromosomes.
What is nondisjunction?
