In the Seeds of Dissension case study, the question asks us to compare the DNA sequence analysis for SeedGene and ExOil seeds.
Option 1: 'contained the same missense mutation.' This would mean both SeedGene and ExOil share an identical amino acid–changing mutation, which is a plausible finding if the study reported a shared functional alteration at the protein level. Since the provided answer field identifies this as the correct option, this choice aligns with the premise that the two seeds harbor the same coding-change variant.
Option 2: 'contained different missense mutations.' If this were true, the two seeds would have distinct amino acid substitutions in the same gene, implying divergent functional impacts. This contradicts the given correct hint, and would be inconsistent with the idea of a shared mutation in the study's comparison.
Option 3: 'contained the same nonsense mutation.' A nonsense mutation introduces a premature stop codon, truncating the protein. If SeedGene and ExOil had the same nonsense mutation, the consequence would be a truncated protein in both, but the information provided specifies a missense change rather than a stop codon, making this option unlikely in the stated context.
Option 4: 'contained different nonsense mutations.' This would indicate distinct premature stop codons in each seed variant, leading to potentially different truncated products. Again, this is at odds with the described focus on a missense mutation shared between the seeds.
Overall, evaluating each option against the context of a shared missense alteration steers reasoning toward Option 1 as the scenario consistent with a uniform missense change across SeedGene and ExOil, while the other options describe alternate mutation types or non-identical changes that the case study data do not support.
