What this chapter covers:
Type A: Interpreting Griffith's Experiment
Type B: Identifying the Transforming Principle
Problem:
Given:
Answer:
❌ Mistake 1: Confusing Griffith's experiment with Avery-MacLeod-McCarty experiment.
❌ Mistake 2: Incorrectly assigning radioactive labels in the Hershey-Chase experiment.
Create a timeline of the experiments, noting the key scientists, experimental designs, and conclusions. This will help you remember the sequence of discoveries.
What this chapter covers:
Type A: Calculating Base Composition
Type B: Describing DNA Structure
Problem:
Given:
Answer:
❌ Mistake 1: Forgetting that A pairs with T and G pairs with C.
❌ Mistake 2: Confusing the 3' and 5' ends of a DNA strand.
Draw a diagram of a DNA double helix, labeling all the components, including the sugar-phosphate backbone, nitrogenous bases, and hydrogen bonds.
What this chapter covers:
Type A: Describing Nucleosome Structure
Type B: Understanding Levels of Chromosomal Organization
Problem:
Given:
Answer:
❌ Mistake 1: Confusing histones with other DNA-binding proteins.
❌ Mistake 2: Not understanding the different levels of chromosomal organization.
Create a visual representation of the different levels of DNA packaging, from the double helix to the mitotic chromosome.
What this chapter covers:
Type A: Describing Chromatin Remodeling
Type B: Understanding Histone Modifications
Problem:
Given:
Answer:
❌ Mistake 1: Thinking that all histone modifications activate gene expression.
❌ Mistake 2: Not understanding the role of ATP in chromatin remodeling.
Create a table summarizing the different types of histone modifications and their effects on gene expression.
