Question

the discovery of mitochondrial dna (mtdna) had no effect on which area of scientific investigation?
○ endosymbiotic theory
○ inheritance research
○ forensic science
○ study of cork bark

Explanation:

• The endosymbiotic theory involves the origin of mitochondria, so mtDNA discovery impacts it.
• Inheritance research: mtDNA has maternal inheritance, so it impacts this.
• Forensic science: mtDNA is used in forensic identification, so it impacts this.
• Study of cork bark: Cork bark study (related to plant cell structure, like Robert Hooke's work) has no relation to mitochondrial DNA.

Answer:

D. study of cork bark
