Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, Resistant bacteria: students must explain how mutations in bacterial pathogens can produce antibiotic-resistant strains.

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 mutations in bacterial pathogens can produce antibiotic-resistant strains.. 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 mutations in bacterial pathogens can produce antibiotic-resistant strains.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Resistant bacteria because students must explain how mutations in bacterial pathogens can produce antibiotic-resistant strains. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain how mutations in bacterial pathogens can produce antibiotic-resistant strains, 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..
