description The present invention relates to a DNA information storage method based on natural and non-natural bases, comprising the following steps: extracting data information to be stored; designing a coding table, wherein the coding table is formed by mapping DNA information and data information units; according to split data information, sequentially confirming, in the coding table, DNA information corresponding to the split data information; sequentially arranging the DNA information in hole sites of a physical medium according to a sequence to obtain a DNA information storage carrier; and during reading, reading the DNA information in a mass spectrum mode and decoding the DNA information. According to the storage and reading methods, natural and non-natural bases can be fully utilized, q-ary coding is implemented, and the density is expected to be greater than 8 bits/nt; furthermore, a trouble that DNA needs to be synthesized from the beginning for information storage is avoided; additionally, the method of identi
