(III) transformant recombinants from transformant non recombinants

Selectable markers help in the identification of:

(I) transformants from non-transformants

(II) recombinants from non-recombinants

(III) transformant recombinants from transformant non recombinants

Selectable markers are genetic elements often used in molecular biology to aid in the selection and identification of specific cells or organisms that have taken up a foreign DNA molecule (e.g., plasmid, vector) during a genetic transformation process. These markers allow scientists to distinguish between cells or organisms that have successfully incorporated the foreign DNA (transformants) and those that have not (non-transformants). Additionally, selectable markers can also help identify recombinant organisms from non-recombinants in cases where genetic recombination has occurred.
