What phase of Mitosis?
Prophase
What phase of Mitosis?
Metaphase
What phase of Mitosis?
Anaphase
What phase of Mitosis?
Telophase
What phase of Mitosis?
- DNA condenses into 23 distinct pairs of chromosomes
- Nuclear membrane disperses
- Each pair is joined together by a protein bridge called a telomere
Prophase
What phase of Mitosis?
- Chromosomes align themselves midway between poles
Metaphase
What phase of Mitosis?
- Chromosome pairs separate and move toward opposite poles
Anaphase
What phase of Mitosis?
- Nuclear membrane begins to form and chromosomes decondense into chromatin
- Cell membrane begins pinching eventually cleaving in two (cytokinesis)
Telophase
What is a Centromere?
A protein bridge
Chromosomes deondense into _______
Chromatin
Cytokinesis
