3. Explain how cellular division (mitosis) functions to form new cells and maintain complex organisms.
4. Describe the role of mitosis in asexual reproduction and explain how it maintains the chromosome number, and how it may contribute to limiting genetic variation.
5. Compare and contrast binary fission, budding, and mitotic cell division.
6. Explain how a mutation might cause the cell cycle to be altered to allow for uncontrolled cell growth.
7. Describe the components and structure of DNA.
8. Describe the process of DNA replication and how the similarities in the genetic codes of organisms are due to common ancestry.
9. Describe the gene and chromosomal mutations in the DNA sequence.
