Question

apply principles of building proteins to health
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.

Explanation:

To be sure a section of DNA encodes for a protein, writing down the sequence to predict the amino - acid chain can help. The genetic code determines which amino acids are linked together based on the DNA sequence. Transcribing DNA to RNA and seeing the resulting protein is also a valid approach as this mimics the natural process of protein synthesis. Comparing the faulty protein to the DNA directly is less straightforward as the relationship is indirect through transcription and translation. Writing down the sequence is a more immediate way to analyze the potential protein - encoding ability of the DNA.

Answer:

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