Question

the discovery of mitochondrial dna (mtdna) had no effect on which area of scientific investigation?

• endosymbiotic theory
• forensic research
• genetic science
• study of cork bark

Explanation:

• Endosymbiotic theory: mtDNA evidence supports this theory that mitochondria originated from ancient bacteria, so it was impacted.
• Forensic science: mtDNA is used for identity testing (e.g., missing persons cases), so this area was affected.
• Study of cell death: mtDNA plays a role in pathways like apoptosis, so it influenced this research.
• Phenomenology research: This is a qualitative philosophical/ social science approach focused on subjective experiences, unrelated to molecular biology discoveries like mtDNA.

Answer:

phenomenology research
