Challenge Problems

Push your limits with challenges.

Question 1

Consider a situation where a scientist is trying to introduce a gene into a bacterial strain with antibiotic resistance. However, bacteria are also developing resistance. What implications does this have for the selection process?

💡 Hint: Think about the relationship between selectable markers and natural evolution.

Question 2

A researcher used a marker gene linked to color change in a plant population. Explain the benefits and drawbacks of using visual screening in this context.

💡 Hint: What could lead to incorrect conclusions in visual screening?
