Bacteria exposed to UV light have a higher rate of mutation than those that have not been exposed. Researchers claim that these mutations cause genetic variations among the bacteria.

Question

Bacteria exposed to UV light have a higher rate of mutation than those that have not been exposed. Researchers claim that these mutations cause genetic variations among the bacteria.
Is this conclusion supported by the evidence?
(1 point)
• No, because a higher rate of mutation does not translate to genetic variations.
• No because UV light only affects cellular functions, not genetic structures.
• Yes, but only if the mutations do not affect bacteria's survival.
• Yes, because UV light is a known mutagen that can alter DNA.

GPT-4o mini · Answer

The correct answer is:

• Yes, because UV light is a known mutagen that can alter DNA.

This conclusion is supported because UV light is known to cause DNA damage, which can result in mutations. These mutations can lead to genetic variations within a population of bacteria.
