We'd like to keep the ONPC for possible class expts. this semester, if you don't mind.
I've been busy preparing for courses, so have done no more expts this week -- Martha has repeated several of the UV expts
with identical results.
Incidentally, we overlooked a good possibility in the interpretation of the decline in maximal rate of adapting cells following
UV treatment. It could be a statistical phenomenon, if one assumes an all-or-none effect of UV in the adaptive mechanism.
Offhand, I don't see any good way of deciding between this and the destruction of precursor.
