Mitosis is really interesting because it helps cells divide while keeping everything the same. Here’s how it works:
DNA Copying: Before a cell splits, it makes a copy of all its DNA. Each piece of DNA, called a chromosome, creates a twin, which we call sister chromatids.
Lining Up: Next, during a stage called metaphase, these sister chromatids line up in the center of the cell. This step is super important to make sure everything divides evenly.
Pulling Apart: Then, in a stage called anaphase, the chromatids get pulled apart to opposite sides. This way, each new cell ends up with a complete set of chromosomes.
Finishing Up: After a stage called telophase, you have two new cells, and each one has the same genetic information.
This process is really important for helping us grow and heal!
