Webground of nonrecombinant clones because all religated vectors can be transformed into host cells and yield clones showing the phenotype of the reporter. There-fore, several approaches that use genes which are toxic for the host cells have been developed (4–7). This re-sults in a powerful selection for vectors with insert DNA. WebAug 19, 2024 · Level P vectors and end-linkers are similar to level M, but all BpiI sites and BsaI sites are reciprocally exchanged. In addition, level P vectors have a different antibiotic selectable marker: Kan R instead of Spec R (Fig. 6). As for level M constructs, cloning in level P vectors requires selecting a suitable level P vector and an end-linker.
