Which option gives the correct cause-and-effect relationship for The development of understanding of genetics and evolution, Theory of evolution (biology only): students must explain why Darwin’s theory was controversial and only gradually accepted.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Theory of evolution (biology only) because students must explain why Darwin’s theory was controversial and only gradually accepted.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Theory of evolution (biology only).

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Theory of evolution (biology only) because students must explain why Darwin’s theory was controversial and only gradually accepted.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Theory of evolution (biology only) because students must explain why Darwin’s theory was controversial and only gradually accepted. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must explain why Darwin’s theory was controversial and only gradually accepted, so the answer must stay inside Theory of evolution (biology only). 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..
