Which option correctly contrasts the named ideas for Variation and evolution, Genetic engineering: students must explain concerns about effects of GM crops on wild flowers, insects and human health.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must explain concerns about effects of GM crops on wild flowers, insects and human health.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Genetic engineering.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must explain concerns about effects of GM crops on wild flowers, insects and human health.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must explain concerns about effects of GM crops on wild flowers, insects and human health. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain concerns about effects of GM crops on wild flowers, insects and human health, so the answer must stay inside Genetic engineering. 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..
