Method of detecting and characterizing a nucleic acid or a sequence of the latter, and enzymatic reactant for the application of this method

摘要

Method for detecting the possible presence of a DNA fragment, notably of a gene, in the midst of a complex sample of nucleic acids. It comprises the hybridization of the sought fragment with a RNA probe, this being, prior or subsequent to the hybridization reaction, modified by an enzyme. Application to seeking of particular genes or DNA fragments in the midst of a biological sample.
