How do the stages of mitosis and meiosis occur in a specific order and never alternate.

The cell divides by the two main process known as mitosis and meiosis. The somatic cells divide by the process of mitosis and germ cells divide by the process of meiosis.

The cell follows the sequential pathway - prophase, metaphase, anaphase and telophase. This specific order follows because the cell cycle have various check point at each stage of the cell cycle. The cyclins and cdk's regulate the transitions from one stage to another stage of the cell cycle. If the cell correctly passes these transition without any defects in the cell.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
