UV Sensitive Yeast Experiment

How does UV light damage DNA?

State one reasons why yeasts are model systems to study the effects of UV light. Hint, there is more information on the next page.

What type of yeast cannot repair its DNA when exposed to UV light?

The yeast was spread on the plate in what type of pattern?

Write down one observation that you have about all the plates.

Write down one observation that you have about the UV sensitive yeast with SPF 15

Some things you can mention: yeast growth on the plate (a lot, a little, no growth)

Write down one observation that you have about the UV sensitive yeast with SPF 70

Some things you can mention: yeast growth on the plate (a lot, a little, no growth)

Write down one observation that you have about the UV sensitive yeast that was covered in tin foil

Some things you can mention: yeast growth on the plate (a lot, a little, no growth)

Write down one observation that you have about the UV sensitive yeast that was not covered (fully exposed to the UV radiation)

Some things you can mention: yeast growth on the plate (a lot, a little, no growth)

Write down one observation that you have about all four UV sensitive plates.

Some things you can mention: yeast growth on the plate (a lot, a little, no growth)

In your response, be sure to state if the hypothesis was supported and provide 2 pieces of evidence.

Be sure to state if the claim is supported or not supported. Provide reasoning with evidence from the lab.
