Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, Theory of evolution (biology only): students must appreciate that evolutionary theory developed over time from evidence gathered by many scientists.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must appreciate that evolutionary theory developed over time from evidence gathered by many scientists.. 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 contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must appreciate that evolutionary theory developed over time from evidence gathered by many scientists.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must appreciate that evolutionary theory developed over time from evidence gathered by many scientists. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must appreciate that evolutionary theory developed over time from evidence gathered by many scientists, so the answer must stay inside Theory of evolution (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..
