Question

Hoe does Mitosis and Meiosis relate / impact Organelles (nucelus, nuceleous, ect...)

Answer 1

both mitosis and meiosis involves spindle fibre. Spindle fibre is a microtubule filament, in other words they are made of microtubulin monomers.

Before entering wither mitosis or meiosis process, cell will enter interphase which includes G1 phase (cell grow in size, making more its organelles so that daughter cells will have enough organelles), S phase (DNA is synthesised at this stage) and G2 phase( cell continues to grow).

Prophase is when the nuclear membrane breakdowns. Chromatins condense into chromosome. Metaphase is when the chromosomes aligns at the equator. Anaphase is the splitting of chromosome and the sister chromatids move towards each pole. Telophase is when chromatids start to loosen and nuclear membrane reforms.

How does mitosis and meiosis relate?
Hmm, gamete cells are formed by meiosis because meiosis aims to half the chromosome number (that's why gamete cells are haploid) and create genetic variations because of crossing over during prophase 1, random independent assortment during metaphase, and the chromosome segregates randomly during anaphase 2 ( you would not know which gamete receives which allele).
Then, when 2 gametes ( one for father, one from mother), the original chromosome number is restored so the zygote is diploid. The zygote undergoes mitosis so that more diploid cells are made.

I hope this helps. Correct me if i'm wrong.
