Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, Resistant bacteria: students must explain how the population of a resistant bacterial strain rises and spreads.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Resistant bacteria because students must explain how the population of a resistant bacterial strain rises and spreads.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Resistant bacteria.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Resistant bacteria because students must explain how the population of a resistant bacterial strain rises and spreads.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Resistant bacteria because students must explain how the population of a resistant bacterial strain rises and spreads. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain how the population of a resistant bacterial strain rises and spreads, so the answer must stay inside Resistant bacteria. 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..
