2. Cell division (1)<br /><br />- Prokaryotes divide by **binary fission**. By contrast, in eukaryotes, cell division occurs in two stages: **mitosis** (nuclear division) and **cytokinesis** (cytoplasmic division).<br /><br />- The **genetic** information is contained in **chromosomes** made up of DNA and proteins. After DNA replication, each chromosome consists of two identical **chromatids** attached at an area called the **centromere**.<br /><br />- The number of chromosomes varies from one species to another. Almost all human cells contain **46** chromosomes. Only gametes contain **23** chromosomes.<br /><br />- During the cell cycle, a cell grows, prepares for division (during **interphase**), and divides to form two daughter cells (during the **M phase**), each of which then begins the cycle again.<br /><br />- The cell cycle can be divided into different stages: M phase (**mitosis** and **cytokinesis**) and Interphase (**G1**, **S**, and **G2** phases).<br />
