Question

The discovery of mitochondrial DNA (mtDNA) had no effect on which area of scientific investigation?
A)endosymbiotic theory
B)inheritance research
C)forensic science
D)study of cork bark

Answer 1

Answer: d

Explanation:

Answer 2

It did not have an effect on study of cork bark.

• Mitochondria are found mostly in eukaryotes. They are absent from single-cell organelles like RBCs.
• They're made up of tiny round mitochondrial DNA. Endosymbiotic hypothesis is responsible for formation of mitochondria and chloroplast in evolutionary terms.
• Plants have bark and cork as an exterior layer. Cork cambium, cork, cortex, and phelloderm make up the majority of the bark.
• Cork barks are dead plant cells with mitochondrial DNA that isn't active in metabolic activities.
