heya...!!!

✔here is ua answer:

_________________________________________❤

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. ... These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase.Stages of mitosis: prophase, metaphase, anaphase, telophase.

hope it helps...!!!!❤

In single celled organisms cell reproduction gives rise to the next generation. In multicellular organisms cell division occurs not just to produce a whole new organism but for growth and replacement of worn out cells within the organisms. Cell division is always highly regulated and follows a highly orchestrated series of steps. The term cytokinesis refers to dividing a cell in half, while mitosis and meiosis refer to two different forms of nuclear division. Mitosis results in two nuclei that are identical to the original nucleus. Meiosis on the other hand results in four nuclei that each have ½ the chromosomes of the original cell. In animals meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm.

Mitosis

Mitosis is a continuum of changes but biologists like break down the stages of mitosis into four main stages, prophase, metaphase, anaphase and telophase.

The focus in this class is on an understanding of the process and not a memorization of phases.

The only phase name you will need to remember is metaphase.

In mitosis the nuclear membrane is broken down, spindle fibers (microtubules) attach to the chromatids at the centromere and pull apart the chromatids.

When the chromatids reach separate ends of the cells the spindle fibers disintegrate and a nuclear membrane rebuilds around the chromosomes making two nuclei.

Each nucleus is identical to the original nucleus.
