plss give me the answer
Dear Student,
- In S-phase, whole DNA replication occurs inside the cell, it is also called synthesis phase. While in G2 phase, the cell grows more and produces proteins for mitosis to occur.
- During Metaphase-I, the bivalent chromosomes align on the equatorial plate attached by spindle to the opposite poles. While in Anaphase-I, the homologous chromosomes separate by constraining of the spindle towards the opposite poles while sister chromatids remains attached to the associated centromeres.
- During zygotene stage of prophase, chromosomes starts to pair with each other and in pachytene, recombination nodules appear and crossing over takes place between non-sister chromatids.
