Mitosis+Phases



Interphase: The chromosomes are doubled. Prophase: When the chromosomes are developing and the fibers that are attached to the centrioles then attach to the chromosomes. Metaphase: The duplicated chromosomes line up in the center of the cell. The chromosomes become attached to the spindle fibers. Anaphase: The spindle fibers pull the two chromosomes away from each other. Telophase: Spindle fibers untwist and now not visible. The chromosomes develop their own nuclear membrane. Cytokinesis: In Cytokinesis, it is very important that the chromosomes and genes are carefully maintained from parent to two daughter cells.

a. What is produced during mitosis? During mitosis cells divide, resulting in two daughter/identical cells. It begins with a single parent cell.

b. Why must body cells go through mitosis? Bodies must go through mitosis to grow and develop, when a cell becomes damaged and needs repair and when a cell needs to be replaced. Your body also heals itself through this process.

c. Mitosis occurs by in a step by step sequence. Predict what would happen if a step was missed or the sequence got out of order. Explain your answer. If a step was missed or got out of order, then I predict that mitosis would fail to result in two daughter cells. The body won't grow or develop, and when a cell becomes damaged and needs repair or replacement, it won't be able to repair and replace these. All of these are reasons why mitosis needs to occur, so if any steps were unsuccessful, the human body would work and function differently. If mitosis continuously fails, it may even lead to death because these phases are needed to develop and grow, repair and replace. It is especially important for Cytokinesis to occur precisely because it is very important for the chromosomes and genes are carefully maintained from parent to two daughter cells.
