<p>Method for analyzing DNA sequences. It comprises the fixing at one of the ends of such DNA a ribonucleotide carrying a molecule covalently fixed and carrying a modification group which may be coupled with an enzyme, allowing a further visualization thereof in presence of a terminal DNA transferase, treating said DNA with different chemical agents allowing to operate differential cleavages within such DNA at the basis, which are also of respectively distinct natures, collecting and separating the DNA fragments carrying the visualizable groups in a system allowing to sort them by the size, and determining the unmodified terminal nucleotides of said DNA fragments, considering the nature of the chemical agents used for the cleavage at their respective levels.</p> |
