After reading the paragraph below, answer the question that follows.
Mitochondria contain their own small genome that contains information to make ribosomal RNAs, transfer RNAs, and a few proteins. Interestingly, the mitochondrial genome has a different genetic code than nuclear DNA. Occasionally, mitochondrial DNA escapes the mitochondrial compartment and enters the cytosol and nucleus.
-What would happen to the extra mitochondrial DNA inside of the cell's nucleus?
A) It could be transcribed and translated into functional proteins.
B) It could be transcribed and translated into nonfunctional proteins.
C) It could be transcribed but not translated.
D) It could not be transcribed.

Quizplus · Accepted Answer

Since the mitochondrial genome uses a different genetic code than nuclear DNA, any proteins produced from it in the nucleus would likely be nonfunctional due to the mismatch in genetic codes.
