Chromatids are attached to one another.
Metaphase chromosomes become aligned.
Chromosomes are grouped during telophase.
The nucleus is located prior to mitosis.
New spindle microtubules form.
A chromosome in G1 of the cell cycle
A replicated chromosome
A chromosome found outside the nucleus
A special region that holds two centromeres together
Another name for the chromosomes found in genetics
Microtubule organizer region
Mitosis produces new nuclei with exactly the same chromosomal endowment as the parent nucleus.
Mitosis may occur without cytokinesis.
Mitosis and cytokinesis are required for asexual reproduction.
All cells come from a preexisting cell.
The mitotic spindles in prokaryotic cells are composed of microtubules.
Cell membrane synthesis
Spindle fiber formation
Nuclear envelope breakdown
Formation of telophase nuclei
Synthesis of chromatids
The centrioles move toward opposite poles.
The nucleolus can no longer be seen.
The nuclear envelope disappears.
Chromosomes are duplicated.
The spindle is organized.
Condensing of chromosomes.
Uncoupling of chromatids at the centromere.
Formation of a spindle.
Synthesis of DNA.
Disappearance of the nucleolus.
A single large nucleus.
High concentrations of actin and myosin.
Two abnormally small nuclei.
Two nuclei but with half the amount of DNA.
The spindles contain microfibrils in addition to microtubules, whereas animal spindles do not contain microfibrils.
Sister chromatids are identical, but they differ from one another in animals.
A cell plate begins to form at telophase, whereas animals a cleavage furrow is initiated at that stage.
Chromosomes become attached to the spindle at prophase, whereas in animals chromosomes do not become attached until anaphase.
Spindle poles contain centrioles, whereas spindle poles in animals do not.
The daughter cells have half the amount of cytoplasm and half the amount of DNA.
The daughter cells have half the number of chromosomes and half the amount of DNA.
The daughter cells have the same number of chromosomes and half the amount of DNA.
The daughter cells have the same number of chromosomes and the same amount of DNA.
The daughter cells have the same number of chromosomes and twice the amount of DNA.

It is highly folded within the cell.
It has genes that control binary fission.
