Which option correctly contrasts the named ideas for Reproduction, DNA structure (biology only): students must explain that the order of bases controls the order of amino acids in a protein.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must explain that the order of bases controls the order of amino acids in a protein.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in DNA structure (biology only).

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must explain that the order of bases controls the order of amino acids in a protein.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must explain that the order of bases controls the order of amino acids in a protein. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain that the order of bases controls the order of amino acids in a protein, so the answer must stay inside DNA structure (biology only). The alternative options are wrong because they either calling a gene a whole chromosome., explaining protein coding without naming the gene as the relevant section of dna., or drift away from when asking about genes, test a section of dna, protein coding, alleles, or inherited characteristics..
