Explanation:
An internal signal peptide also known as signal sequence, targeting, transit peptide et cetera is usually a 16-30 amino acids.
This is present at the N-terminal of the newly formed proteins which are destined towards the secretory pathway.
This protein has the ability to get modified and produced in the form of enzymes or proteins.
These proteins include those who reside in the Golgi body or endoplasmic reticulum.
