because it has been proposed that the ribosome-membrane interaction is different in endoplasmic reticulum derived from a non-secretory and secretory cell we undertook a study to determine whether attachment of the ribosome to the membrane involved ribosomal rna and if the rrna in ribosomes derived from the two classes of cell possessed an altered susceptibility to rnaase ( ribonuclease ) hydrolysis .
