Arrange the following steps in sequence of their occurrence in the process of genetic modification of an organism.
(A) Cutting of desirable genes and vector DNA by molecular scissors.
(B) Introduction and maintenance of recombinant DNA in the host cell.
(C) Identification of DNA sequence with desirable gene.
(D) Linking of desirable genes with vector DNA.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (C), (A), (D), (B)
Genetic modification begins by identifying the DNA with the desirable gene (C), then cutting the gene and vector with restriction enzymes (A), joining them (D), and introducing the recombinant DNA into the host (B).
