Question

Quizplus · Accepted Answer

The presence of lysine, arginine, and histidine in a protein suggests that it is likely a nuclear-encoded protein that is transferred to mitochondria from cytosolic free ribosomes. Proteins that are encoded by mitochondrial or chloroplast genes would typically not have these amino acids enriched in particular regions because they would have evolved to use different amino acids that are more abundant in those organelles. The fact that the protein is transported to the mitochondrion through the secretory pathway is not necessarily related to its amino acid composition.
