CATEGORISING NUCLEIC ACID

摘要

Provided is a method for categorising nucleic acid, which method comprises producing a nucleic acid population by action of an endonuclease on double-stranded nucleic acid, such that each nucleic acid in the nucleic acid population has a double-stranded portion, contacting the nucleic acid population with one or more oligonucleotide sequences, and isolating nucleic acid which correctly hybridises to an oligonucleotide sequence, wherein each oligonucleotide sequence has a pre-determined recognition sequence, the nucleic acid being categorised by its ability to correctly hybridise to oligonucleotide sequences having the recognition sequence, the recognition sequence being situated such that it recognises a sequence in the double-stranded portion of the nucleic acid, one or more different recognition sequences being represented in the oligonucleotide sequences.
