Mitosis and the Cell Cycle Explained

The Cell Cycle and Mitosis

Cells grow Bigger, Increase their Mass and carry out normal Cell Activities. They then Replicate their DNA to form Two Copies of each Chromosome ready for Cell Division. They also increase the number of sub-cellular structures such as Mitochondria, Ribosomes and Choloroplasts

Mitosis - In this process, one set of Chromosomes is pulled to each end of the Dividing Cell and the Nucleus Divides

The Cytoplasm and The Cell Membranes also Divide to form Two Identical Daughter Cells

New Cells are needed for an Organism, or part of an Organism to grow. They are also needed to Replace worn out Cells and to Repair Damaged Tissue. however, the New Cells must have the same Genetic Information as the originals so they can do the same job.

Each Cell has a Nucleus that contains Chromosomes. Chromosomes Carry Genes that contain the instructions for making All the New Cells, Tissues and Organs needed to make a New You!

A Gene is Information that controls a Characteristic, or Part of a Characteristic, of your body. It is a Section of DNA, the unique Molecule that makes up your Chromosomes

Most of your Characteristics are the Result of Many Different Genes rather than a single Gene. The Genes are grouped together on chromosomes.
