Proteins coded for by nuclear DNA but found within mitochondria move from the cytoplasm into mitochondria using ________.
A) signal sequences (peptides)
B) random transport vesicles
C) attachment of ribosomes to outer mitochondrial pores and direct deposition into the inner mitochondrial compartment
D) mRNAs that are manufactured in the nucleus but translated by mitochondrial ribosomes

Question

Quizplus · Accepted Answer

Proteins targeted for mitochondria contain a specific signal sequence that directs them to the correct organelle. These signal sequences are recognized by receptor proteins on the outer mitochondrial membrane, which then transport the protein across the membrane and into the mitochondrial matrix.
