52.The vector requires a gene whose expression helps in identifying and eliminating non-transformants. This gene is known as: A. Origin of replication B. Structural gene C. 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.
