Viruses implicated in the woodiness disease of South African passionfruit, and the molecular characterization of a new potyvirus
… antibody sandwich enzyme-linked imunoassay and nucleic acid hybridization. In transmission studies, the CMV-isolate and the potyvirus were found to be sap, aphid and graft transmissible. Separation of the two viruses was achieved by passage through a selective host range.

M6A Reshapes the Folding and Recognition Landscape of RNAs
<p>Ribonucleic acid (RNA) is a versatile and dynamic biomolecule that serves as an indispensable component in the central dogma of molecular biology. The realization that RNA plays a wide variety of roles in gene expression and regulation has been accompanied by the discovery that virtually all …

Characterization of Oligonucleotide Microarray Hybridization: Microarray Fabrication by Light-Directed in situ Synthesis – Development of an Automated DNA Microarray Synthesizer, Characterization of Single Base Mismatch Discrimination and the Position-Dependent Influence of Point Defects on Oligonucleotide Duplex Binding Affinities
The present thesis focuses on nucleic acid hybridization between free-floating target sequences and complementary end-tethered oligonucleotide probes on the surface of DNA microarrays. Hybridization experiments were performed on oligonucleotide microarrays (DNA Chips) which were fabricated with an …

DNA-DNA Checkerboard Hybridization to Identify Bacteria in Human Plaque Samples
… probes were used with a checkerboard DNA-DNA hybridization scheme to analyze whether human plaque samples contained any of the 15 bacterial species. Our results have shown that this method is successful in identifying bacterial DNA present in the subgingival patient plaque samples. Probe …
