Study Guide: Control of Gene Expression

Overview

This study guide covers the essential aspects of gene expression control, including mutations, cell specialization, stem cells, transcription factors, cancer biology, and genetic technologies.

Important Topics

1. Mutations

• Understand how mutations can lead to changes in protein structure and function.
• Be able to explain the impact of specific mutations on phenotype.

2. Cell Specialization

• Differentiate between totipotent, pluripotent, multipotent, and unipotent stem cells.
• Explain the significance of induced pluripotent stem cells in medicine.

3. Transcription Regulation

• Describe the role of transcription factors and how they can stimulate or inhibit transcription.
• Discuss the role of oestrogen in gene expression.

4. Epigenetics

• Explain how DNA methylation and histone acetylation affect gene expression.
• Understand RNA interference and its role in inhibiting translation.

5. Cancer Biology

• Distinguish between benign and malignant tumours.
• Explain the roles of tumour suppressor genes and oncogenes in cancer development.

6. Genetic Technologies

• Familiarize yourself with recombinant DNA technology and its applications.
• Understand the principles of PCR and its use in DNA amplification.
• Learn about genetic screening and genetic fingerprinting techniques.

Study Tips

• Create flashcards for key terms and concepts.
• Practice explaining concepts in your own words.
• Work through past exam questions related to gene expression.
