How is the sequence written in the gene patent, and what does the previous string of numbers mean?

There are only four letters in the gene sequence, namely, A, C, G and T, which respectively represent the four nucleotides that make up DNA. Adenine, cytosine, guanine and thymine, any string of nucleotides with a length greater than 4 is called a sequence, each letter represents a base, and two bases form a base pair, and the pairing law of base pairs is fixed.

The primary structure of real or imaginary DNA molecules carries genetic information represented by a series of letters in partial DNA sequences or gene sequences.
