the present paper describes an assessment of three methodological criticisms of rna-efflux measurements that are made for the former reason : for such measurements , it is sufficient to show that the post-incubation supernatant rna is similar overall to homologous cytoplasmic mrna , rather than to nuclear rna , that is nevertheless of intranuclear origin , and that alterations to the medium during experiments do not markedly perturb this general nuclear restriction .
