Part 1: explain the similarities and differences between mitosis and meiosis and give an example that occurs in the world around
KatRina [158]

PART 1:

There are two types of cell division in eukaryotic cells:

* mitosis, which ensures the birth of cells identical to the mother cell during asexual reproduction. It gives diplide cells (2n). It takes place in one division.  It can be done by somatic cells.

* meiosis, a characteristic of male and female reproductive cells, which results in the production of sexual cells or gametes (haploid cell (n)) for reproduction. It takes place in two succesive divisions.

For points in common, both are preceded by the replication of DNA. They have the same divisional steps, and both involve eukaryotic cells.

PART 2:

The stages of division (for mitosis and meiosis) are:

Prophase: It is during this phase that the DNA condenses in the form of chromosomes.

Metaphase: It is then that the collection of condensed chromosomes at the equator of the cell occurs to form the equatorial plate.

Anaphase: During this very fast phase, the sister chromatids separate and migrate to the opposite poles of the cell.

Telophase: This is the last phase of mitosis, the chromatids are now at the two opposite poles of the cell and it begins to split in two.

For meiosis there is a second division, so we speak of prophase II, metaphase II, anaphase II and telophase II.
