Verified step by step guidance

Understand that the question asks for a method that uses DNA to classify organisms based on genetic similarities and differences.

Recall that DNA sequencing involves determining the exact order of nucleotides in a DNA molecule, which allows comparison of gene regions among different species.

Recognize that methods like measuring metabolic rates or observing physical traits do not directly analyze DNA sequences and thus are less precise for genetic classification.

Note that analyzing protein folding patterns relates to protein structure, which is downstream of DNA but not a direct method for classifying organisms based on their DNA.

Conclude that DNA sequencing to compare gene regions among species is the method that directly uses DNA information to classify organisms genetically.
