Introduction to Mitosis

Reproduction is a crucial, and complex, process. As we have seen in Chapter 5, DNA has a method of reproducing itself, called replication. In Chapter 18, we will discuss the process of human reproduction. In this chapter, we will focus on the cellular level of reproduction: how eukaryotic cells divide.
On the cellular level, the parent cell needs to copy the DNA and give enough cytoplasmic components (enzymes, organelles, etc.) to the daughter cells to ensure their survival. There are two types of cellular division, mitosis and meiosis. Mitosis occurs in the body, or somatic, cells, and meiosis occurs in the reproductive, or germ, cells. Although the outcomes of these two processes are different, their mechanisms are very similar. Meiosis will be covered in Chapter 18, and mitosis will be discussed here.
