Without this addition, a truncated lipopolysaccharide is synthesized, and survival of bacteria treated with hydrophobic antibiotics decreases. Previous investigations, including tryptophan fluorescence … Read more
Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: One major source of extragalactic X-rays are X-ray binaries, when a star orbits a compact object – a black hole, neutron star, or white dwarf. As material falls from the star onto the compact object, it loses gravitational potential and heats up enough to emit … Read more
Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: The nucleosome is the basic unit of chromatin which folds to form chromosomes, the final structure in which DNA is packaged in the cell. Nucleosomes consist of DNA wrapped around an octamer of four histone proteins, resulting in a bead on a string type structure. … Read more
