At what phase of mitosis does the centromere separate and chromatids become individual chromosomes that move to opposite sides of the cell?
B) Anaphase
Anaphase:
stage of cell division in which the chromosomes move away from one another to opposite poles of the spindle.
Prophase: first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
Metaphase: second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.
Telophase: the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
What is the difference between mitosis and meiosis?
B) Mitosis doubles the number of chromosomes while meiosis haves the number of chromosomes.
