Characterization of the Mechanistic Roles of Rif1-Glc7 in DNA Double-Strand Break Repair Pathway Choice in Saccharomyces cerevisiae
(University of Waterloo, 2023-05-10)Rap-1 interacting factor 1 (Rif1) is a protein involved in telomere regulation, DNA replication and has more recently been found to mediate genomic stability by influencing the choice of DNA double-strand break (DSB) repair ... -
Characterization of the nodulation phenotype of E151, a pleiotropic pea (Pisum sativum L.) mutant.
(University of Waterloo, 2008-01-16)E151 (sym15) is characterized as a pleiotropic pea (Pisum sativum L.) mutant. It has been described as having short lateral roots, a short primary root, and a shorter epicotyl than that of the wild type Sparkle. Furthermore, ... -
Characterization of the pro-apoptotic function of eIF5A in human cancer cell lines
(University of Waterloo, 2007-09-18)Eukaryotic translation initiation factor 5A (eIF5A) is the only known protein containing the unique amino acid, hypusine. eIF5A is present in all eukaryotic cells and is highly conserved, but its function is not well ... -
Characterization of the role of Orc6 in the cell cycle of the budding yeast <em>Saccharomyces cerevisiae</em>
(University of Waterloo, 2006)The heterohexameric origin recognition complex (ORC) acts as a scaffold for the G1 phase assembly of pre-replicative complexes. Only the Orc1-5 subunits are required for origin binding in budding yeast, yet Orc6 is an ... -
Characterization of the Self-Assembly of Pyrene-Labelled Macromolecules in Water
(University of Waterloo, 2010-05-19)The self-assembly of several pyrene-labelled amphiphilic macromolecules in water was characterized by fluorescence. Information on their self-assembly was obtained by monitoring the level of pyrene aggregation in solution. ... -
Characterization of Three-Level Control in Capacitively-Shunted Flux Quantum Circuits Using Randomized Benchmarking
(University of Waterloo, 2021-05-12)Superconducting devices have emerged as leading candidates for building practical quantum computers, owing to their scalability, designability, and ease of control. Development of superconducting devices has been accompanied ... -
Characterization of Two Novel Voltage-gated Calcium Channel Beta Subunits from Lymnaea stagnalis
(University of Waterloo, 2010-03-01)In excitable tissues, voltage-gated calcium channel activity is critical in the linkage of electrical stimuli to physiological responses, and so modulation of calcium channels therefore has significant implications. The ... -
Characterization of Various Pyrene-Labelled Macromolecules in Solution by Fluorescence
(University of Waterloo, 2010-11-04)Time-resolved fluorescence was applied to linear and branched pyrene-labelled macromolecules to study their internal dynamics. The linear macromolecules consisted of two series of pyrene-labelled poly(N-isopropylacrylamide)s ... -
The characterization of γH2AX and p53 as biomarkers of genotoxic stress in a rainbow trout (Oncorhynchus mykiss) brain cell line
(Elsevier, 2018-06-01)Rainbow trout cell cultures were exposed to three genotoxicants and examined for effects on γH2AX and p53 levels by western blotting and on cell viability using the indicator dyes Alamar Blue (AB) for energy metabolism and ... -
The characterization of γH2AX as a biomarker of genotoxicity in Oncorhynchus mykiss
(University of Waterloo, 2017-05-19)Environmental contamination due to by-products and waste from industrial activities is a growing universal concern, especially regarding the impact on water and the aquaculture industry. Conventional tests to diagnose ... -
Characterization on PAR-3 in early Xenopus laevis development
(University of Waterloo, 2013-01-24)Polarized cell movements are essential to the cell rearrangements that occur during morphogenesis. In Xenopus, cell polarity is reflected in the directional cell intercalations that drive the morphogenetic movements ... -
