Quizplus · Accepted Answer

A signal sequence is a short peptide present at the N-terminus of the majority of newly synthesized proteins that are destined towards the secretory pathway. These sequences are typically composed of 9-12 hydrophobic amino acids and can include positively charged residues, directing the protein to the endoplasmic reticulum in eukaryotes or the plasma membrane in prokaryotes.
