Question
Which of the following cannot cause mutations?Products produced by cells involved in chronic inflammationRadiation from the sunChemical mutagens found in the environmentTranscription errors by RNA polymerase
Solution
Transcription errors by RNA polymerase cannot cause mutations. This is because mutations are changes in the DNA sequence, and while RNA polymerase can make errors during transcription, these errors do not change the underlying DNA sequence. Instead, they may result in the production of a faulty protein. On the other hand, products produced by cells involved in chronic inflammation, radiation from the sun, and chemical mutagens found in the environment can all cause changes in the DNA sequence, and thus, can cause mutations.
