Biology - Mitosis Flashcards
When do the centrioles move apart and organize into spindles?
Prophase
When do chromosomes coil and appear as long threads, then move to the equator?
What breaks down and disappears during Prophase?
Nuclear membrane
What part of the cell eventually becomes invisible?
Nucleolus
Which phase is the slowest?
Prophase
What part of the cell has disappeared by time it reaches Metaphase?
Nuclear membrane
Which phase is the fastest?
Anaphase
What happens during Metaphase?
The centromere of each double-stranded chromosome attach to a spindle fibril at the spindle equator
Which phase do the centromeres divide and move to the opposite poles of the spindle?
Anaphase
When does cytokinesis occur?
Anaphase
When do new nuclear membrane form?
Telophase
What happens to the chromosomes during Telophase?
They become larger, thinner, and less distinct
What reappears during Telophase?
Nucleolus
What is replicated during Telophase?
Centrioles
When is cytokinesis nearly complete?
Telophase
