Scientists develop a genetically modified plant species that has a nonfunctional protein. The protein is necessary for the plant to use nitrogen. The species has a single mutation in a gene.

Question

What does this tell us about the relationship between DNA and proteins?

Responses

Nitrogen is vital for plant species survival.
Nitrogen is vital for plant species survival.

Mutations in DNA are always harmful to organisms.
Mutations in DNA are always harmful to organisms.

Changes in DNA can affect protein function.
Changes in DNA can affect protein function.

Proteins are not related to DNA.

Answer 1

The correct response is:

Changes in DNA can affect protein function.

This illustrates the relationship between DNA and proteins, as a mutation in the DNA can lead to a nonfunctional protein, which in this case affects the plant's ability to utilize nitrogen.
