Synthesis of total RNA, DNA, and protein was followed in a
haploid yeast auxotroph during starvation for required amino acids
and uracil, and during shift-up and shift-down conditions.
During amino acid starvation, synthesis of macromolecular
constituents was not immediately affected, reflecting the presence
of large intracellular amino acid pools. Under...
Studies were carried out to elucidate the mechanism of enzymatic
control of methionine biosynthesis in Saccharomyces cerevisiae.
Enzymatic studies demonstrated that, in addition to the methionine
activating enzyme, the S-adenosylmethionine:homocysteine
transmethylase enzyme was induced during cultivation in the presence
of excess methionine. A similar, though reduced effect was
observed when...
Concern over the low enrollment in homemaking classes prompted this study of the homemaking program in secondary schools in Bend, Oregon. Two questionnaires were constructed to obtain the opinions and beliefs of ninth, tenth, and eleventh-grade girls in Bend, Oregon, and their parents about the following: 1. What factors influence...
Two methods for the estimation of non-esterified fatty acids in
plasma were evaluated. An attempt was made to obtain a reliable
micro-technique to estimate these acids in blood fractions.
The titrimetric method of Trout et al. was satisfactory in the
analyses of pure fatty acids and fatty acids added to...
One of the most beautiful and geologically interesting parts of the Oregon coast is in the vicinity of Cape Arago near Charleston, 10 miles west of Coos Bay. Three very fine state parks have been developed here. They are (from north to south): Sunset Bay, Shore Acres, and Cape Arago...
At the time of the eruptions of Lassen Peak in 1914-1915, an
area of vegetation along the east slope of the mountain approximately
1 1/4 miles wide and four miles long was destroyed. Except for a
few surviving trees, all vegetation was destroyed.
A study of the revegetation of this...
