in order to characterize the rna fractions of the two nuclear components , nucleoli and chromatin , and to determine thereby the precise localization of the rna typical of isolated nuclei , time-courses of p ( 32 ) incorporation into nucleolar , chromosomal , and cytoplasmic rna of drosophila salivary glands have been determined from autoradiograms .
