8. An mRNA cOding for a secretory protein, when translated using free riboSome under in vitro conditions, resulted in a 40 kDa protein. The same mRNA when translated using the rough endoplasmic reticulum resulted in a 36 kDa protein. The difference in the molecular weight of the two polypeptides is due to the loss of a (a) 2 kDa peptide from N-terminus and a 2 kDa peptide from the C-terminus kDa peptide from the C-terminus 4 kDa peptide from the C-terminus (b) 1 kDa peptide from N-terminus and a 3 (c) 4 kDa peptide from the N-terminuss (d)
