Cell in prophase manual#

Still, very rarely mistakes in copying or dividing chromosomes are made, and these mistakes can have negative consequences for cells and for people. Each replicated chromosome in the cell lines up along the metaphase plate. In the first stage, prophase, each chromosome. Fortunately, our cells have amazing systems to copy chromosomes almost perfectly and to make sure that one copy goes to each daughter cell. The mitosis (M) phase of the cell cycle has four sequential stages: prophase, metaphase, anaphase, and telophase.

We need each of our cells to receive exactly one copy of each chromosome, and each copy needs to be perfect, no mistakes, or the cells may have trouble following the genetic instructions. Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. Check out what the mitosis phases look like under a microscope. This occurs during the four steps of mitosis, called prophase, metaphase, anaphase and telophase. Metaphase I: Instead of all chromosomes pairing up along the midline of the cell as in mitosis, homologous chromosome pairs line up next to each other. Otherwise, we might not be able to follow the instructions and things could go wrong. At the end of interphase, the cell has duplicated its chromosomes and is ready to move them into separate cells, called daughter cells. We don't want to accidentally give one person two copies of page four and one person zero copies of page four.

Cell in prophase manual#

With our instruction manual example, it is really important that each person gets one copy of every page. In mitosis, a cell copies each chromosome, then gives one copy to each of two daughter cells. Copy each page, then give one copy to each of two people. We can think about mitosis like making a copy of an instruction manual.
