  1. Ch.10 How cells divide Davyn Leon. Clinton Lewis, Patrick Davis, Ryan Brown

  2. 10.1: Bacterial Cell Division • Binary fission is the cell division of bacterial cells • Begins with the replication of bacterial DNA at a specific site. • After it is replicated it is partitioned in the cell • After the cell enlongationFtsZ protein assembles into a ring and facilities into a ring and facilities septation and cell division

  3. 10.2: Eukaryotic Chromosomes • Walther Flemming in 1879, while looking at the rapid division of salamander larvae. • He called their cell division mitosis • Most eukaryote have 10-50 chromosomes • Humans have 46 or 23 pairs of chromosomes inside them. • The chromosome is broken down into different parts- the DNA wraps around a histone core, many of these or compressed together and form solenoids then their even compressed more to form a chromatin loop, which from the rosettes of chromatin loops,, and last there put together to from the chromosome

  4. 10.3 overview of the eukaryotic cell cycle • The cell cycle is put into five phases • 1. gap phase 1 • 2. synthesis • 3. gap phase 2 • 4. mitosis • 5. cytokenisis

  5. 10.4 interphase: preparation of mitosis • There are some key parts before mitosis • The first thing is the separation of the kinetochore of the sister chromatids

  6. 10.5 M phase: chromosome segregation and the division of cytoplasmic contents • There are five stages of mitosis • 1. prophase • 2. prometaphase • 3. metaphase • 4. anaphase • 5. telophase • And the last step but is separate is cytokinesis
