Chromatin DNA sequences intimately associated with the "core"
of the basic, repeating chromatin subunit are shown to be relatively
resistant to digestion by micrococcal nuclease. Chromatin DNA
sequences lying between adjacent chromatin subunits, as well as
DNA sequences in regions of chromatin which are free of chromatin
subunits, are subject...
The cytolytic properties of the mosquitocidal 25 Kd protein deltaendotoxin of Bacillus thuringiensis subsp. israelensis (Bti) was studied using the human erythrocyte as a target cell. Both a fixedtime and a kinetic hemolytic bioassay were developed in order to screen a variety of treatments for their influence on the toxinerythrocyte...
The genome of the multicapsid nuclear polyhedrosis virus of
Orgyia pseudotsugata (OpMNPV) was mapped by examining overlapping
Hindlll fragments from cosmid clones which had been constructed
from partial Hindlll digests of viral DNA. Five OpMNPV cosmid
clones containing fragments encompassing the entire OpMNPV genome
were hybridized to blots of DNA...
