The Transfer of Radioactive Phosphorus From Parental to Progeny Phage

Abstract
When progeny phage particles of T2r+ with the use of mutant B1l of Escherichia coli strain B and containing 30% of the parental P32 were used to infect unlabeled bacteria, only 30% of the label was transferred to the progeny (2d generation expt.). This finding is contrary to Putnam and Kozloff''s hypothesis that 30% transfer might be due to a bipartite structure of the phage, a genetic and a non-genetic part, in which case there should have been 100% transmission.
