end-group analyses reveal that , after short-term labelling , adenosine is the principal 3'-hydroxyl terminus in all centrifugal subfractions of 'rapidly labelled ' i [ 3h ] rna , whereas cytidine ( in 5.8s rrna ) , guanosine ( in 18s rrna ) and uridine ( in 26s rrna ) are the principal 3'-hydroxyl termini in centrifugal subfractions of wheat embryo i [ 3h ] rna .
