‘Vhis was a discovery of great importance that convinced the
phage group, but tt was not original. As early as 1944 Oswald
Avery and lis colleagues at the Rockefeller Institute, New
York, had reported transfer of the ability to synthesize a
specific polysaccharide capsule from one bacterial type of
Pneumococcus to another by means of extracted and hights
purified DNA. Avery suggested, very tentatively, that DNA
might be the genetic material, Both Delbruck and Luria knew
of this work some time before its publication and found it
interesting but failed to see its significance. Uhis was under-
standable at the ame since, although it had been known from
the end of the last century that DNA and protein were closely
associated in the chromosomes of higher organismis, the
chemical structure of DNA, unlike that of protein, appeared
to be too simple to carry complex information. Moreover,
Avery's phenomenon seemed remote from the problems pre-
sented by phage and had been revealed by biochemical tech-
niques with which most phage workers were out of tune.'?
