What happens during prophase?
Options
- AChromosome condensation
- BDNA replication and chromosome duplication
- CCentrioles does not move to the opposite poles
- DNormal metabolism
Correct answer
A. Chromosome condensation
Step-by-step solution
Mitosis is also divided into four stages namely prophase, metaphase, anaphase and telophase Chromosome condensation occurs during prophase. Simultaneously, the centrioles move to the opposite poles. The nuclear envelope and the nucleolus disappear and the spindle fibres start appearing. Metaphase is marked by the alignment of chromosomes at the equatorial plate. During anaphase the centromeres divide and the chromatids start moving towards the two opposite poles.
