Replication of plasmid molecules containing a single
adenovirus terminal sequence and specially arranged
inverted repeat sequences were studied. When the plasmids
were linearized to expose the adenovirus terminal sequence
and transfected into 293 cells with helper adenovirus DNA,
a larger molecule was detected. The new molecule
contained adenovirus terminal sequences...
The goal of this study was to better understand stream communities through a perspective that might make their structure, organization, and development more understandable. This goal was approached
through the following objectives:
1. To determine the assemblages of stream organisms and define subsystems within a stream community.
2. To explain...
Some elementary teachers want to be more child-centered in their
teaching. They are trying to consider the needs of the students
before the coverage of curriculum. Much of the inspiration for this
educational approach has come from the British primary schools.
The purpose of this study was to see if...
The association of hyaluronic acid (HA) into a double stranded
structure has been investigated by circular dichroism (CD)
spectroscopy into the vacuum ultraviolet region. The CD of HA changes
dramatically, monitoring a cooperative transition as the dielectric
constant of an aqueous solution is reduced by adding organic solvents.
This structural...
Replication of plasmid molecules containing either a left-end or a
right-end adenovirus origin was investigated. When the plasmids were
linearized to expose their respective adenovirus termini, mixed, and
transfected with helper adenovirus DNA into the human 293 cell line, a
new molecule was detected. The new molecule was the size...
The two segments of double-stranded RNA (dsRNA) from
infectious pancreatic necrosis virus (IPNV) were cloned
into plasmid vector pUC8. Two distinct sets of overlapping
clones were identified by restriction enzyme and Southern
blot analysis. Each of these sets was shown, by Northern
blot analysis, to be exclusively related to either...
