Question

A scientist studied the effect of exposing DNA to various wavelengths of ultraviolet light and determined the number of copying errors made
after exposure. The graph shows the scientist experimental results.
DNA Replication Errors
High
DNA Copying Errors
Low
0 200 250 300 350
Ultraviolet Wavelength (nm)
At which of these ultraviolet wavelengths would a mutation in a skin cell most likely occur?

A.225 nm
B.250 nm
C.275 nm
D.300 nm

Answer 1

Answer:

C. 275 nm

Explanation:

At 275 nm of ultraviolet wavelengths causes mutation in a skin cell because at 275 nm of wavelength, maximum DNA Copying Errors occur in the cells that leads to mutation in the cell. A mutation is a kind of change that occurs in the DNA, due to two reasons, due to mistakes that is occur when the DNA is copied or as the result of environmental factors such as ultraviolet radiations.
