Question

mitochondrial disorders can be caused by mutations in all the following except
multiple choice
mitochondrial dna
nuclear dna
ytoplasmic dna

Explanation:

Mitochondrial disorders can be caused by mutations in mitochondrial DNA and also in nuclear DNA (since many mitochondrial - related proteins are encoded by nuclear genes). However, cytoplasmic DNA is not a typical source of mutations causing mitochondrial disorders as mitochondria have their own DNA and nuclear DNA also plays a role, but cytoplasmic DNA is not a recognized contributor in this context.

Answer:

C. cytoplasmic DNA
