Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA ESTIMAR UNA PROPIEDAD O PARAMETRO DE UN MATERIAL DE ACIDO NUCLEICO, ESTANDO LA PROPIEDAD O PARAMETRO RELACIONADO CON LA CONDUCTIVIDAD ELECTRICA DEL MATERIAL DE ACIDO NUCLEICO, QUE INCLUYE MEDIR LA CONDUCTIVIDAD ELECTRICA DEL MATERIAL DE ACIDO NUCLEICO, Y ESTIMAR A PARTIR DE LA MEDIDA LA PROPIEDAD O PARAMETRO DEL MATERIAL HACIENDO REFERENCIA A UNA RELACION PREDETERMINADA ENTRE LA CONDUCTIVIDAD ELECTRICA Y DICHA PROPIEDAD O PARAMETRO. ESTO ESTA BASADO EN EL DESCUBRIMIENTO DE QUE EXISTEN CIERTAS PROPIEDADES IMPORTANTES DE LOS ACIDOS NUCLEICOS, CUYA DETERMINACION CUANTITATIVA RESULTA A MENUDO DESEABLE, QUE PUEDEN EVALUARSE POR MEDIDAS DE LA CONDUCTIVIDAD DE UNA SOLUCION DEL ACIDO O ACIDOS NUCLEICOS. LOS CAMBIOS EN DICHAS PROPIEDADES PUEDEN VERSE REFLEJADOS EN UNOS CAMBIOS CORRESPONDIENTES EN LA CONDUCTIVIDAD ELECTRICA. LA CONCENTRACION DEL ACIDO NUCLEICO EN LA SOLUCION Y EL PESO MOLECULAR DE UNA ESPECIE DE ACIDO NUCLEICO SON EJEMPLO DE UNA PROPIEDAD IMPORTANTEQUE PUEDE SER DETERMINADA.
