What kind of radiation is UV. Light, Ionizing or nonionizing

Nonionizing

1

The mutagenic effect: what are formed in this DNA when it is exposed to this type of radiation

Pyrimidine dimers

2

What specific wavelength of radiation maximizes damage

260nm

3

What was the effect of leaving the lids on during exposure

The lids blocked the UV light

4

What was the control in exercise 18?

UV light was blocked on half of the petri by a notecard

5

Which two bacteria were used in exercise 18?

Staphylococcus aureus

Bacillus megaterium

6

What did the results determine to be true about the two different bacteria in exercise 18

Bacillus Megaterium was more resistant to UV light than S. Aureus

7

How did the results of the two bacteria in exercise 18 differ, and why?

B. Megaterium was more resistant because it is a spore former
