Applying single-molecule force spectroscopy methods we study the presumably highly complex transition which qualitative agrees with the behaviour expected. Moreover, we have found a surprising intermediate state under the presence of Mg2+ ions at low temperature5 p.application/pdfengcc-by-nc-nd (c) Pérez, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/RNATemperatures baixesTreballs de fi de grauRNALow temperaturesBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
