Effects Of The Dihydrouracil Lesion On Dna Using 1h/31p 1d And 2d Solution Nmr, Benjamin M. Boyd
Effects Of The Dihydrouracil Lesion On Dna Using 1h/31p 1d And 2d Solution Nmr, Benjamin M. Boyd
MSU Graduate Theses
The effects of the dihydrouracil lesion in DNA were studied using two dimensional NMR spectroscopy. The sequence used was based off of the Drew-Dickerson Dodecamer, with the cytosine in the three position replaced by a dihydrouracil. All of the nonexchangeable proton chemical shifts, with the exception of the H2, H5’, and H5’’, of the lesioned DNA were identified using NOESY spectra and then compared to the chemical shift values of the Drew Dickerson Dodecamer. The largest differences in chemical shifts were observed in the nucleotides neighboring the lesion, both within the strand and on the opposite strand. The imino exchangeable …

The DNA molecule can be modeled as a quantum logic processor in which electron spin qubits are held coherently in each nucleotide in a logically and thermodynamically reversible enantiomeric symmetry, and can be coherently conducted along the pi-stacking interactions of aromatic nucleotide bases, while simultaneously being spin-filtered via the helicity of the DNA molecule. Entangled electron pairs can be separated by that spin-filtering, held coherently at biological temperatures in the topologically insulated nucleotide quantum gates, and incorporated into separate DNA strands during DNA replication. Two separate DNA strands that share quantum entangled electrons can be mitotically divided into individual cells, …

With the discovery of cisplatin in the 1960s, it has been widely studied as a precursor for anticancer drug development. Despite its effectiveness against certain cancers, clinical usage of cisplatin is restricted by a number of side effects and resistance. In the past decade, scientists have been exploring biologically important ligands such as sugar derivatives in the hope of overcoming such challenges. Attachment of a sugar moiety could facilitate lower accumulation of platinum drugs in the body as well as enhance cellular uptake. In this study, a carbohydrate-linked cisplatin analog, cis-dichlorido[(2-β-D-glucopyranosidyl)propane-1,3-diammine]platinum (5) has been studied. The aim was to evaluate …

The processing of DNA recovered from felony crime scenes often causes delays in trials of up to 3 years, calling into question defendants' rights to a speedy trial. Using Lewin's force field analysis as the theoretical framework, the purpose of this quantitative, comparative study was to compare the processing and reporting of results related to DNA testing in 4 states. Survey data were collected from state bar members (n=137), members of a professional law organization (n=149), and members of a state DNA laboratory (n=20). The purpose of this quantitative, comparative study was to determine whether these variables (interagency communications, staff …

Understanding the relationship between molecular structure and function represents an important goal of undergraduate life sciences. Although evidence suggests that handling physical models supports gains in student understanding of structure–function relationships, such models have not been widely implemented in biochemistry classrooms. Three-dimensional (3D) printing represents an emerging cost-effective means of producing molecular models to help students investigate structure–function concepts. We developed three interactive learning modules with dynamic 3D printed models to help biochemistry students visualize biomolecular structures and address particular misconceptions. These modules targeted specific learning objectives related to DNA and RNA structure, transcription factor-DNA interactions, and DNA supercoiling dynamics. …

DNA (deoxyribonucleic acid) has become an integral part of forensic science in the last couple of decades since its discovery to this application by Alec Jeffreys. Although there have been many advances throughout the years, the time it takes to obtain a DNA profile using conventional methods in a laboratory setting is approximately 24 to 72 hours. Due to this length of time and the increase in demand for DNA testing, it has caused a tremendous amount of backlog throughout the country. In 2009, the FBI (Federal Bureau of Investigation) in collaboration with the US Department of Defense of Homeland …
