Question

Quizplus · Accepted Answer

Mitochondrial and chloroplast genomes encode some of the proteins required for their respective functions (aerobic respiration in mitochondria and photosynthesis in chloroplasts), but not all proteins involved in these processes. They also encode ribosomal RNAs (rRNAs) and transfer RNAs (tRNAs) necessary for protein synthesis within these organelles.
