The vector requires a gene whose expression helps in identifying and eliminating non-transformants. The gene is known as: a. Origin of replication b. Structural gene b. Plasmid d. Selectable marker
Option D. In recombinant DNA technology, selectable markers are the specific genes that are used to identify the transformants from the non-transformants after the process of recombination. These genes are used to detect whether the incorporation of a nucleic acid sequence has been successful into an organism's DNA. These marker genes are resistant to various antibiotics and are used in cloning vectors.
