Question

Quizplus · Accepted Answer

Signal sequences are short amino acid sequences that direct the newly synthesized protein to its correct location within the cell. Proteins destined for the mitochondrial matrix, chloroplast outer membrane, and peroxisomes all have specific signal sequences that facilitate their targeting and import into these organelles. The Golgi membrane is involved in protein sorting and modification, but proteins targeted there do not have a unique signal sequence for direct targeting in the same way as those for the mitochondrial matrix, chloroplast outer membrane, and peroxisomes.
