Integrase catalyzes insertion of a retroviral genome into the host chromosome. Following reverse transcription, integrase binds specifically to the ends of the duplex retroviral DNA, endonucleolytically cleaves two nucleotides from each 3'-end (the processing activity), and inserts these ends into the host DNA (the joining activity) in a concerted manner....
The scope of this thesis consists primarily of
an exposition upon the merits of indirect and. semi-indirect
illumination. In deriving our conclusions, we
have considered two sources of information: firstly,
that of test data from a number of indirect and direct
installations, and. secondly, the opinion of men familiar
with...
In order to better characterize linker histone interactions with DNA, avian erythrocyte-specific linker H5 and the trypsin-resistant globular domain of H5 (GH5) were used in DNA binding studies. To begin, H5 displayed a considerably higher binding
affinity for DNA than the isolated globular domain (GH5), supporting the importance of the...
Pastures consisting of mixtures of subclover (Trifolium
subterraneum) and grasses have responded to sulfur fertilization
on many sites in Douglas County, Oregon. The objectives of this
study were to examine specific changes in forage quality which occur
as sulfur is applied in excess of the amount required for maximum
yield...
A diversity in climate, geologic parent material, and soil
characteristics exist in Jackson, Josephine, Coos, and Douglas
Counties of southwest Oregon. Previous field trials and soil testing
results have revealed uncertainties as to the phosphorus (P) status
of the soils in this area. Twenty-four sites from nine agriculturally
significant soil...
Nitrogen (N), phosphorus (P), and sulfur (S) fertilization
trials with Stephens winter wheat (Triticum aestivum L.) were
conducted on the Columbia Plateau under minimum and no tillage
conditions. The crop rotation was either wheat-summer fallow
(summer fallow) or wheat-wheat (recrop).
Nitrogen variables included: N rates, N timing, and N
source...
The Federal Water Pollution Control Act Amendments of 1972
prohibits the discharge of seafood processing solid wastes into
navigable waters after July 1, 1977. Oregon shrimp and crab processors
must use other methods of disposal for the 15 to 30 million
pounds of solid waste generated annually. The application of...
Several crops grown in the Willamette valley of western Oregon
respond to applications of boron fertilizers. The acid, highly-leached
soils of this area are naturally low in plant-available B. Application
of B to the soil annually or at less frequent intervals is currently
recommended, but the fate of applied B...
