Ls: mitosis and meiosis both produce new cells through cell division. however, the division process differs due to the kind of cell being produced. how is meiosis different from mitosis?

Respuesta :

Mitosis produces two genetically identical diploid cells, on the other hand, Meiosis produces four genetically identical haploid cells.

  • Mitosis: It can be described as the process of division in every living cell. It has four basic stages for division- prophase, metaphase, anaphase, and telophase. The division of cells is based on Asexual Reproduction. The division happens when the nuclear membrane has broken down, and spindle fibers (microtubules) attach to the chromatids at the centromere and pull apart the chromatids. The chromatids reach out to the two separate ends of the cells, then the spindle fibers disintegrate and a nuclear membrane rebuilds around the chromosomes making two nuclei. Both of them are identical to the original nuclei.
  • Meiosis: It is a process of cell division where the daughter cells have half the number of chromosomes as the original cell. In humans, this means that the chromosome reduces from 46 to 23. The joining of both male & female gametes results in restoring chromosomes to 46. In meiosis, homologous chromosomes are separated into different nuclei. Then chromosome number is divided in half. Chromatids are also separated into separate nuclei. Again, it is spindle fibers that “pull” the chromosomes and chromatids apart in meiosis.
