Cell Cycle, DNA Replication and Cancer Test Review
TEKS
5A: Describe the stages of the cell cycle, including deoxyribonucleic acid (DNA) replication and
mitosis, and the importance of the cell cycle to the growth of organisms;
5D: Recognize that disruptions of the cell cycle lead to diseases such as cancer;
6A: Identify components of DNA, and describe how information for specifying the traits of an
organism is carried in the DNA.
Summary of Topics to Review for Unit Test
 DNA- structure and function
 DNA Replication- How and why it replicates
 Cell Cycle- Interphase through cytokinesis. Must know all the steps
 Mitosis- Division of nucleus. Must know all steps and what occurs in each step (PMAT)
 Biomolecules- Carbs, Lipids, Nucleic Acids, Proteins. Structure and function.
 Osmosis- how it works, where the water goes
 Cell Respiration
 Virus- structure and function
 Cell types- prokaryotic vs. eukaryotic; animal vs. plant
