Answer:

46 chromosomes

Explanation:

Chromosomes form after DNA replicates; prior to replication, DNA exists as chromatin. Chromosomes contain genes, which code for proteins. Human cells normally have 46 chromosomes, made up of two sets of chromosomes, one set inherited from each parent.

First, prophase this is when the chromosomes are just chillin in the nucleus that is protected by the nuclear envelope(the purple circle in the blue circle).

Then, metaphase this is when the nuclear envelope breaks down and the chromosomes line up on the metaphase plate in a line.

Then, anaphase this is when the two chromatids that make up one chromosome are pulled apart by spindles.

Then, telophase this is when the spit chromatids start to form new nucleus and causing the cleavage furrow, the line in between the cells that holds them together, to form.

Finally Cytokinesis, this is where you finally get your too new cells.
