Question

Which of the following is the possible routes of mitochondrial genesis?

• A. From other membranous structures
• B. From pre-exising mitochondria
• C. De novo
• D. All of the above

Answer 1

The correct option is D All of the above

Mitochondrial biogenesis is the formation of new mitochondria from pre-existing mitochondria and precursor. It is produced from the transcription and translation of genes both in the nuclear genome and in the mitochondrial genome. The majority of mitochondrial protein comes from the nuclear genome, while the mitochondrial genome encodes most parts of the electron transport chain along with mitochondrial rRNA and tRNA. The parts of mitochondria is assembled by the De novo pathway. Thus, the correct answer is option D.
