In your own words, describe the processes of transcription and translation. Include what happens in each process, and what type of mRNA is involved in each.

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

Transcribe the following DNA into mRNA (use capital letters and include spaces only between each codon set): 
ATG ACT CAT GAT TAT TAG

A DNA sequence is ATG ACT CAT GAT TAT TAG. Translate the codons into amino acids. Use the codon wheel to help you. Select the correct set of amino acids.

• Tyr – Stop – Val – Leu – Ile - lle

• Cys – Thr – Val – Leu – Met - lle

• Tyr – Ile – Val – Pro – Ile - Pro

• Cys – Ile – Val – Pro – Met - Leu
