Difference Between Mitosis And Meiosis

Distinction Between Mitosis And Meiosis


In single-celled organisms, cell replica offers rise to the subsequent era. In multicellular organisms, cell division happens not simply to supply an entire new organism however for development and alternative of worn-out cells throughout the organisms.

Cell division is all the time extremely regulated and follows a extremely orchestrated collection of steps. The time period cytokinesis refers back to the division of a cell in half, whereas mitosis and meiosis refer to 2 completely different types of nuclear division.

Mitosis leads to two nuclei which are an identical to the unique nucleus. Meiosis, alternatively, leads to 4 nuclei that every has ½ the chromosomes of the unique cell. In animals, meiosis solely happens within the cells that give rise to the intercourse cells (gametes), i.e., the egg and the sperm.

Distinction between Mitosis and Meiosis




Every chromosome replicates. The result’s two genetically an identical sister chromatids (Nevertheless, do observe that interphase is technically not part of mitosis as a result of it takes place between one mitotic section and the subsequent) Chromosomes not but seen however DNA has been duplicated or replicated


Prophase -Every of the duplicated chromosomes seems as two an identical or equal sister chromatids, The mitotic spindle begins to kind. Chromosomes condense and thicken Prophase I – crossing-over recombination – Homologous chromosomes (every consists of two sister chromatids) seem collectively as pairs. Tetrad is the construction that’s fashioned. Segments of chromosomes are exchanged between non-sister chromatids at crossover factors often called chiasmata (crossing-over)


Metaphase -The chromosomes assemble on the equator on the metaphase plate Metaphase I Chromosomes regulate on the metaphase plate. Chromosomes are nonetheless intact and organized as pairs of homologues


Anaphase – The spindle fibres start to contract. This begins to tug the sister chromatids aside. On the finish of anaphase, a whole set of daughter chromosomes is discovered every pole Anaphase I Sister chromatids keep intact. Nevertheless, homologous chromosomes drift to the other or reverse poles

Mitosis Overview

  • Mitosis is a steady strategy of cell division which happens in all varieties of dwelling cells.
  • Mitosis entails 4 primary phases – prophase, metaphase, anaphase and telophase.
  • Mitosis is the method the place the division of cell happens by asexual replica.
  • In mitosis, the nuclear membrane is damaged down, spindle fibres (microtubules) connect to the chromatids on the centromere and pull aside the chromatids.
  • When the chromatids attain separate ends of the cells, the spindle fibres disintegrate and a nuclear membrane rebuilds across the chromosomes making two nuclei.
  • Every nucleus is an identical to the unique nucleus because it was in G1.

Meiosis Overview

  • Meiosis is the type of nuclear cell division that leads to daughter cells which have one half the chromosome numbers as the unique cell.
  • In organisms which are diploid, the top result’s cells which are haploid. Every daughter cell will get one full set of chromosomes, i.e., certainly one of every homologous pair of chromosomes.
  • In people, this implies the chromosome quantity is decreased from 46 to 23.
  • The one cells that endure meiosis will grow to be sperm or eggs.
  • The becoming a member of collectively of a sperm and egg throughout fertilization returns the variety of the chromosomes to 46.
  • Cells that endure meiosis undergo the cell cycle together with the S section so start the method with chromosomes that encompass two chromatids simply as in mitosis.
  • Meiosis consists of meiosis I and meiosis II. In meiosis I homologous chromosomes are separated into completely different nuclei.
  • That is the discount division; chromosome quantity is lower in half. Meiosis II is similar to mitosis; chromatids are separated into separate nuclei.
  • As in mitosis, it’s spindle fibres that “pull” the chromosomes and chromatids aside.
  • The tip results of meiosis is 4 cells, every with one full set of chromosomes as an alternative of two units of chromosomes.

Similarities Between Mitosis and Meiosis

  • Each mitosis and meiosis takes place within the cell nuclei which will be noticed underneath a microscope
  • Mitosis and meiosis, each contain cell division
  • Each the processes happen within the M-phase of the cell cycle. In each cycles, the standard levels are metaphase, anaphase, telophase and prophase
  • In each the cycles, synthesis of DNA takes place

  • Meiosis I
  • Meiosis II


The distinction between Mitosis and Meiosis is kind of obvious. They’re two very completely different processes which have two completely different features. Meiosis is required for genetic variation and continuity of all dwelling organisms. Mitosis, alternatively, is targeted on the expansion and developments of cells. Meiosis additionally performs an essential position within the restore of genetic defects in germline cells.
