If cells are grown in a medium containing radioactive 15N, which of these molecules will be labeled?

Question

Quizplus · Accepted Answer

Nucleic acids contain nitrogen, which would be labeled with radioactive 15N if it is present in the growth medium. Proteins also contain nitrogen, so they would also be labeled. Fatty acids do not contain nitrogen, so they would not be labeled in this experiment. Therefore, the correct answer is E, both proteins and nucleic acids.
