Vedclass · Answer

(C) selectable marker is a gene that helps in identifying and eliminating non-transformants and selectively permitting the growth of the transformants.If a plasmid lacks a selectable marker,it becomes impossible to distinguish between cells that have taken up the plasmid (transformants) and those that have not (non-transformants).Therefore,the experiment is negatively affected because the researcher cannot isolate the successfully transformed host cells from the population.
