Described herein is the synthesis of an uncharged stereoregular oligonucleotide
analog consisting of cytosine bases linked at specific intervals to a polyamide backbone
derived from (L)-glutamic acid. Preparation of this analog entailed borane reduction of
(L)- pyroglutamic acid to give optically pure lactam alcohol 9. Tosylation and alkylation
with cytosine...
The purpose of this research was to investigate the
effects of three levels of contextual interference on the
acquisition and retention of a sequential motor skill, by
moderately mentally retarded and nonretarded subjects. The
subjects were functioning between an eight and twelve year
level. The dependent measures included; Reaction Time...
Several laboratories have shown that the VV
replication cycle is dependent on the host cell nucleus.
The basic biological observation is that if the host cell
nucleus is physically removed by cytochalasin B-mediated
enucleation, functionally inactivated by UV-irradiation, or
selectively blocked with a-amanitin, the results are the
same: W is...
The effect of the abundance and rapidity of ectomycorrhiza and root tip formation on
conifer seedling survival and growth was investigated on disturbed forest sites in southwest
Oregon and northern California. Experiments were conducted over a range of
community types and environmental conditions. A range of sources of transfer soil...
