They … Epub 2017 Aug 5. This was determined by ultracentrifugation and gel electrophoresis, methods based on different physical principles. I wanted to get my children thinking about the process of investigation today, so we talked about how we could test whether some structures were stronger than others using DUPLO. Stable maintenance is only observed when the complete plasmid has a size no larger than that of the rDNA unit (9.1 kb). The results suggest that for cationic lipid compositions (DOTAP/DOPE and DOTAP/cholesterol), 1.5 M NaCl, but not 0.15 M NaCl, both prevent lipoplex formation and/or induce partial dissociation between lipid and DNA of preformed lipoplexes. These three methods used in this study are good tools for studying interactions of DNA with cationic liposomes of different lipid compositions with salt and biological fluids such as serum. The results indicate that either the electrostatic association between DOTAP/cholesterol and DNA is weaker as a result of factors such as intimacy of interaction, or level of hydration than that between DOTAP/DOPE and DNA, or that in DOTAP/DOPE–DNA there are forces in addition to electrostatics, which play a role. Relate theses factors to the level of stability. Factors affecting the mitotic stability of high-copy-number integration into the ribosomal DNA of Saccharomyces cerevisiae. 416. Please enable it to take advantage of the complete set of features! Date de publication 1 juin 2015. Present studies show that, indeed, DNA in permeabilized metaphase cells, in contrast to cells in interphase, when exposed to buffers of low pH (1.5-2.8) becomes digestible with the single-strand-specific S1 or mung bean nucleases. This lecture explains about different factors required for DNA stabilization including temperature, pH and salt concentrations. March 19, 2012 By Emma Vanstone 13 Comments. SDS below its critical micellar concentration (CMC) induced “de-condensation” of DNA without its physical release (assessed by ultracentrifugation) for both DOTAP/DOPE and DOTAP/cholesterol lipoplexes. Department of Biochemistry and Molecular Biology, The Pennsylvania State University College of Medicine, Hershey, PA, USA. 2012; 165(4):414-23 (ISSN: … … Very interestingly, the IL ions disrupt the water cage around DNA, including the spine of hydration in the minor groove. https://doi.org/10.1016/j.chemphyslip.2012.03.006. The main bonding in DNA which renders the double helix structure so stable is that of hydrogen bonds. The present data indicate that structural proteins extractable with greater than or equal to 1.2 N NaCl may be involved in anchoring DNA to the nuclear matrix or chromosome scaffold and may be responsible for maintaining a high degree of chromatin compaction in situ, such as that observed in metaphase chromosomes or in G0 cells. Cell treatment with NaCl at a concentration of 1.2 N and above abolished the difference between interphase and mitotic cells, rendering DNA in mitotic cells less sensitive to denaturation; such treatment also resulted in decondensation of chromatin visible by microscopy. E. coli is the most frequently used host for production of enzymes and other proteins by recombinant DNA technology. A variety of extraction procedures and enzymatic treatments provided evidence that the presence of histones, HMG proteins, and S-S bonds in chromatin, as well as phosphorylation or poly(ADP)ribosylation of chromatin proteins, can be excluded as a factor responsible for the differential sensitivity of metaphase vs interphase DNA to denaturation. DNA segments sensitive to single-strand-specific nucleases are present in chromatin of mitotic cells. Electronic Theses and Dissertations. Discrimination of Adsorbed Double-Stranded and Single-Stranded DNA Molecules on Surfaces by Fluorescence Emission Spectroscopy Using Acridine Orange Dye. COVID-19 is an emerging, rapidly evolving situation. These interactions are few relative to the major factors, but are still have some importance for protein stability. Lopes, I. de Wijs, S.I. How Chemical Mutagens Can Affect Your DNA Dr. David Jernigan, Hansa Center If you consider yourself a fairly typical American consumer, buying most of your personal care products such as shampoo, soaps, perfumes, deodorants, lotions, toothpaste, and the like, from your local grocery store, then I can guarantee you with a certainty that you are damaging your genetic blueprint…your DNA. For example, mutations in the base sequence that result from errors that occur during DNA replication can result in mismatches tha… Following dissociation of histones, the high spatial density of the charged DNA polymer may induce topological strain on the double helix, thus decreasing its local stability; this can be detected by metachromatic staining of DNA with AO or digestion with single-strand-specific nucleases. SDS, however, caused large changes in DNA condensation state in both DOTAP/DOPE–DNA and DOTAP/cholesterol–DNA lipoplexes. This partial dehydration … En vigueur. The data from earlier cytochemical studies, in which the metachromatic fluorochrome acridine orange (AO) was used to differentially stain single vs double-stranded DNA, suggested that DNA in situ in intact metaphase chromosomes or in condensed chromatin of G0 cells is more sensitive to denaturation, induced by heat or acid, than DNA in decondensed chromatin of interphase nuclei. Biochemical Mediators and Mechanisms Involved in Chromatin Conformational Remodeling through the Cell Cycle. An increase from 7–22% to ∼61% in level of EtBr intensity in DOTAP/DOPE–DNA lipoplex was observed after SDS treatment; and in DOTAP/cholesterol–DNA, EtBr fluorescence intensity increased upon SDS treatment from 6% to 40–50%. Techniques such as PCR and DNA microarray that are based on hybridization of nucleic acids are indispensable to life science research. This structure gives DNA physical and chemical properties that make it very stable. The results demonstrate that plasmid size is an important, but not the only, determinant of mitotic stability. Under the conditions found in cells, DNA adopts a double helix structure. The results indicate that either the electrostatic association between DOTAP/cholesterol and DNA is weaker as a result of factors such as intimacy of interaction, or level of hydration than that between DOTAP/DOPE and DNA, or that in DOTAP/DOPE–DNA there are forces in addition to electrostatics, which play a role.

Factors affecting DNA binding and stability of association to cationic liposomes. In addition, we found that a cross‐linked gel matrix is not required for the stabilization of CAP‐DNA complexes, that comparable stabilization is produced by three dissimilar polymers (linear polyacrylamide, dextran and polyethylene glycol), and that these polymers stabilize complexes more effectively than equivalent weight concentrations of their cognate monomers. NIH Factors affecting the mitotic stability of high-copy-number integration into the ribosomal DNA of Saccharomyces cerevisiae. Lopes, I. de Wijs, S.I. We also proved that the helper lipid affects level and strength of the L+ and DNA− electrostatic association; these interactions are weaker for DOTAP/cholesterol than for DOTAP/DOPE, despite the fact that the positive charge and surface pH of DOTAP/cholesterol and DOTAP/DOPE are similar. The stability of the DNA double helix depends on a fine balance of interactions including hydrogen bonds between bases, hydrogen bonds between bases and surrounding water molecules, and base-stacking interactions between adjacent bases.
