A gene whose expression helps to identify transformed cell is known as
Open in App
Solution
The correct option is B Selectable marker
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. Thus the correct answer is option B.
