Talk about the protein import to chloroplast.

Similar to mitochondria up to 100 proteins are encoded by chloroplast DNA, however proteins are also translated by free ribosomes of the cytosol and imported to one of the six subcompartments of the chloroplast (ICM, OCM, Intermembrane space, lamella lumen, lamella membrane, stroma) Proteins have a very specific address code that takes it towards the specific subcompartment where it will do its job (transported by translocases TOC (outer membrane) and TIC (inner protein) in addition it involved chaperons that help folding and processing in stroma.) address code is at N terminous.
