Beschreibung
Zusammenfassung:	The invention belongs to the technical field of biological detection, and provides a probe for detecting mononucleotide mutation and application thereof. The probe provided by the invention is in a configuration that a DNA tetrahedron is connected with four X-type structures, the tetrahedron structure is composed of four nucleic acid chains, and the 3'end of each chain is modified with a fluorophore; each X-type structure is composed of three nucleic acid chains and a tetrahedron 5'end, and a left-up nucleic acid chain is modified with a quenching group; each X-type structure is far away from the nucleic acid chain Right-down of the tetrahedron and is provided with a foothold, target DNA can be recognized and paired with the target DNA, the X-type structures are opened, the nucleic acid chain with a quenching group is released, and a fluorescence signal is recovered. According to the specific value of the initial fluorescence signal to the fluorescence signal after the reaction, the detection of the helicobac
