Abstract: A method of writing data to a DNA strand comprises cutting an address block of a selected address-data block unit of the DNA strand to form first and second DNA strings, and inserting a replacement address-data block that includes a replacement data segment between the first DNA string and the second DNA string to provide a rewritten DNA strand having valid address followed by valid data and an invalid address followed by invalid data.
