The nature of the association of U1 RNA with rapidly sedimenting RNP structures in rat hepatoma nuclei was investigated. The effects of salt and proteinase K treatment on the stability of this 'bound' form of U1 RNA were studied using sucrose density gradient analyses. Quantitation of the amount of
## Abstract Nuclei and nucleoli isolated from calf liver contain acidβprecipitable putrescine, spermidine and spermine conjugates. The polyamines are released upon peptide bond hydrolysis. All of the nuclear putrescine conjugate and a major portion of the polyamine conjugates are localized within t
