You are in a laboratory attempting to identify a genetic defect responsible for a disease. You believe you have located the gene that results in a faulty protein—but you aren't sure!

How could you be sure you have located a section of DNA that encodes for a protein?

Write down the sequence to see what amino acids might be linked together.

Allow the DNA to be transcribed to RNA and see what protein results.

Compare the faulty protein to the DNA.
