In this video, our group will talk about what mitosis is, why it is important, and why we should learn about mitosis. We will then go over each step of mitosis.

Mitosis, as defined by the Merriam Webster dictionary, is a process that takes place in the nucleus of a dividing cell. It involves a series of steps consisting of prophase, metaphase, anaphase and telophase. This results in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus.

Why is mitosis important?

Mitosis is an essential part of the growth and development for all living things, from the smallest unicellular organisms like amoebas and bacteria to complex organisms like plants and animals.

In this video we will focus on the mitosis of a typical eukaryotic animal cell. For simplicity, we will focus on the nucleus of the cell.

Some describe this stage as the “resting stage”.

However, that is not entirely true. The white circle here symbolises the cell and the big orange circle inside the white circle symbolises the nucleus. Inside the nucleus, the cell prepares itself for mitosis. At the start of interphase, the cell’s DNA exists in the form of a uncondensed chromatin.

Each chromatin duplicates into two daughter chromatids through semiconservative DNA replication. At the end of interphase, we will get pairs of sister chromatids which is represented by the pairs of yellow and green lines (and indicated by the red arrow).

The centrosome (indicated by the pink T-shaped structure) will also be duplicated.

Aster, a type of microtubule (indicated by the pink strings), extends from the
