when inactive, denatured, virus RNA is incorporated into a reconstituted nucleoprotein. It should be emphasized that the present data do not, in our opinion, permit a choice between the foregoing alternative explanations. The possibility that small amounts of otherwise inactive virus RNA components may, when incorporated into DNA-bearing nucleoproteins, render the polymer infectious is subject to experimental verification. The same is true of the alternative proposal that TMV protein may induce some biological activity in an indifferent nucleic acid incorporated into a reconstituted nucleoprotein. It is hoped that such investigations will permit an unequivocal explanation of the results just described. We wish to thank Mrs. Katherine Baker, Mrs. Ellen E. Richman, and Mrs. Georgia B. Shearer for assistance in carrying out these experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
