附件里fig1的说明如下:
FIG. 1. Schematic of the LINK method of tandem plasmid construction. a, LINK sequence. Restriction sites are shaded in gray, and base pairs corresponding to T4 DNA polymerase exonucleolytic stop sites are shaded in orange (see below). b, construction of tandem plasmids. Plasmids are digested with SwaI or PacI, followed by heat-inactivation, treatment with T4 DNA polymerase in the presence of dGTP or dCTP, respectively, to form 5 overhangs, mixing of plasmids, and transformation into E. coli.
