What is the importance of the codons UAA, UAG, and UGA?

• They signal the protein to start forming

• They cause mutations in the protein

• They signal the protein to stop being formed

• They are used to signal a problem with the protein

What is a mutagen?

• an agent that causes a genetic mutation

• a mutation in a gene

• a man-made substance that is used to fix DNA

• an extra component in transcription that makes changes to DNA
