Question

Discuss how ultra violet light works as a mutagen. This could include:
- What is UV light and the Mutations commonly introduced by UV light? What are the Repair mechanisms in yeast that fix damage caused by UV light?
- Describe the phenotypes of Saccharomyces Cerevisiae plates, the first plate is the control yeast, while the second plate has been exposed to low UV light, the third plate has been exposed to high UV light. Normal yeast has round smooth white colonies. Are there any signinifcant differences?

### Analysis of UV Radiation Effects on Yeast Growth

This image displays three petri dishes used in an experiment to observe the effects of UV radiation on the growth of *Saccharomyces cerevisiae* (a species of yeast).

1. **Petri Dish 1: Control (No UV)**
- Labeled as "S. cerevisiae Control"
- The dish shows multiple yeast colonies, indicating normal growth conditions without UV exposure.

2. **Petri Dish 2: Low UV Exposure**
- Labeled as "S. cerevisiae Low UV"
- Fewer colonies are visible compared to the control, suggesting that low UV exposure inhibits some yeast growth.

3. **Petri Dish 3: High UV Exposure**
- Labeled as "S. cerevisiae High UV"
- Very few colonies can be seen, demonstrating that high UV exposure significantly inhibits or kills the yeast, preventing colony formation.

This experiment highlights the damaging effects of increased UV exposure on yeast cells, which could have broader implications for understanding UV damage in other biological organisms.
