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

The correct answer will be option- study of cork bark.

Explanation:

Mitochondria is an organelle of the cell which is involved in the production of the ATP molecules.  

The mitochondria are thought to have evolved from the endo-symbiosis of chemo-synthetic bacteria to the cell. The mitochondria contain their own DNA molecules which help in their replication. The discovery of mitochondrial DNA also leads to the studies in the field of inheritance pattern of the cells as well as it also leads to the research in the field of forensic science.

The mitochondria study has no effect on the cork cells as the cork cells are dead cells and contain no cytoplasm.

Thus, option-study of cork bark is the correct answer.
