Which option correctly contrasts the named ideas for Variation and evolution, Genetic engineering: students must interpret information about genetic engineering techniques and make informed judgements about cloning, genetic engineering and GM crops.

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 interpret information about genetic engineering techniques and make informed judgements about cloning, genetic engineering and GM crops.. 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 interpret information about genetic engineering techniques and make informed judgements about cloning, genetic engineering and GM crops.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must interpret information about genetic engineering techniques and make informed judgements about cloning, genetic engineering and GM crops. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must interpret information about genetic engineering techniques and make informed judgements about cloning, genetic engineering and GM crops, 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..
