WebSep 1, 1996 · Gene targeting is a powerful method for introducing mutations into the genome of embryonic stem cells. The most widely used approach is the positive-negative selection method in which a gene encoding a negative selection marker is cloned into the replacement vector to obtain an enrichment of properly targeted clones. WebIn a typical cloning experiment, researchers first insert a piece of DNA, such as a gene, into a circular piece of DNA called a plasmid. This step uses restriction enzymes and DNA ligase and is called a ligation. After a ligation, the next step is to transfer the DNA into bacteria in a process called transformation. WebSelectable markers are used to select for successful transformants, from untransformed cells, they provide a survival advantage to the cells containing exogenous DNA. It is necessary to select for the survival of transformants since the number of transformed cells is very less in the total population of treated cells [32]. lasten neuvola iisalmi
