temperature-shift experiments using metabolic inhibitors of dna ( cytosine arabinonucleoside , 20 mug/ml ) , rna ( actinomycin d , 5 mug/ml ) , and protein synthesis ( cycloheximide , 2 x 10 ( -4 ) to 10 x 10 ( -4 ) m ) were used to investigate the requirements for ongoing dna , rna , and protein synthesis in the distribution of virion protein between the nucleus , nucleolus , and cytoplasm .
