Study Guide #4 for Biology 1201, section 4
Objectives: Students should be able to define and understand the following terms and concepts.
I’ve listed the material I would like you to learn for chapters 11, 18-19, 45 and 48. I will only cover the
material listed in each chapter.
Chapter 18, Concepts 18.1, 18.2, 18.5
pages 351-364, 373-377
1. Transcription regulation in bacteria
2. Bacterial promoters, operons
3. The trp operon (Figure 18.3)
4. The lac operon (Figure 18.4, 18.5)
5. Gene expression in eukaryotes – overview (Figure 18.6)
6. In humans, most cells have the same DNA content. However gene expression is different. For example, a
liver cell expresses different genes than a nerve cell.
7. Some proteins such as hemoglobin are present in a single type of cell.
8. Signalling pathways can regulate cell growth (Figure 18.24)
9. Errors in signaling pathway can lead towards cancer protooncogene, oncogene, and tumor suppressor
10. Cancer progression (Figure 18.25)
11. Test your understanding 1, 2, and 6
Chapter 19, Concepts 19.1, 19.2
Pages 381-390
1. What is a virus?
2. Viral life cycles – lytic growth and lysogenic growth (Figures 19.5 and 19.6)
3. RNA versus DNA containing viruses (Table 19.1 don’t memorize this table though)
4. Reproduction of an enveloped RNA virus (Figure 19.7)
5. Reverse transcriptase (page 388)
6. HIV replication (Figure 19.8)
7. Test your understanding 1, 3, 4
Chapter 21, Concept 21.4 (pages 434-438)
Also Figure 20.8 page 404
1. Repetitive DNA (Figure 21.7)
2. Transposons and retrotransposons (Figure 21.9)
3. Gene families (Figures 21.10 and 21.13)
4. Test your understanding 4
Chapter 11, pages 206-218
Concepts 11.1, 11.2 and 11.3
1. Hormones and signal transduction
2. Paracrine and endocrine signaling (Figure 11.5)
3. G-proteins and receptor tyrosine kinases (Figure 11.7)
4. Phosphorylation cascade (Figure 11.10)
5. cAMP and what it does (Figures 11.11, 11.12)
6. Amplification (Figure 11.16)
7. Test your understanding 1, 2, 5, 7
Chapter 45, pages 974-980, 989-990
Concepts 45.1, 45.2, 45.4 (part)
1. Hormone action, endocrine system (Figures 45.6 and 45.9)
3. Homeostasis and negative feedback control(Figure 45.13 and 45.20)
