Dear Gus:

Just a random thought~-hoped you might have some information.

It occurred to me that there might be something in common between
lysogenicity and lysis inhibition. There is a great deal of difference,
of course, in many aspects. But would it be feasible to see whether an
lysis~inhibited infected cell can be "induced" by mild doses of UV
as in the Lwoff effect with lysogenic bacteria? Has this ever been
tried? ~—- would you?

Sincerely,

Joshua Lederberg
