Method for permanently embedding identity card number into genome

Abstract

The invention provides a method for permanently embedding the ID number into the genome. One is to permanently insert the exogenous gene fragment containing the ID number into the genome through CRISPR technology, and the other is to insert the specific DNA containing the ID number into the genome. Separated to read. This allows permanently stored DNA to remain identifiable, even if the outer packaging label is lost or misinterpreted. It can likewise be used for microbiological preservation of microorganisms, including bacteria and viruses. For example, for the SARS virus, if an inactivated SARS virus gene sample can be left behind, it can be used for future research.

Description

technical field [0001] The invention belongs to the field of gene extraction, transportation and preservation, and in particular relates to a method for permanently embedding an ID card number into a genome. Background technique [0002] The current gene extraction, transportation and storage mainly rely on the labels on the test tubes. Due to the many links, the labels written on the outside of the test tubes are easy to be mistaken or worn out. Ensuring that the identity of a gene can never be mistaken is crucial to the establishment of a national gene bank. Therefore, we have to permanently paste the ID number edited with DNA on the gene. In this way, even if the test tube does not have any label, as long as the sample is there, the ID number is there. [0003] There are currently two ways to convert data information into DNA information for permanent storage. One is not to insert the gene sequence directly into the genome, but to mix the chemical substance with the ge...

Problems solved by technology

One is not to insert the gene sequence directly into the genome, but to mix the chemical substance with the genome sample, and use the structure of the chemical substance to represent the data information. The disadvantage of this method is that when analyzing the data information, not only the detection of the chemical substance , but also to test the genome sample, which is more troublesome

[0004] The other is not to use the CRISPR-Cas9 method, but directly use the restriction enzyme cutting method to cut the genome and then connect the sequence representing the ID number to the genome. The disadvantage of this method is that the base of the restriction enzyme is only 4- 6, so the accuracy of targeting cannot be guaranteed
