Which option gives the correct cause-and-effect relationship for Classification of living organisms, Classification of living organisms: students must describe the traditional classification of living organisms into groups using structure and characteristics.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Classification of living organisms because students must describe the traditional classification of living organisms into groups using structure and characteristics.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Classification of living organisms.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Classification of living organisms because students must describe the traditional classification of living organisms into groups using structure and characteristics.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Classification of living organisms because students must describe the traditional classification of living organisms into groups using structure and characteristics. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must describe the traditional classification of living organisms into groups using structure and characteristics, so the answer must stay inside Classification of living organisms. The alternative options are wrong because they either treating dna as if it always means one gene., calling a gene a whole chromosome., or drift away from when asking about dna, test molecular structure, base sequence, nucleotides, or genetic information storage..
