हिन्दीGiven below are two statements: Statement I: Three basic steps in genetically modifying an organism include identification of DNA with desirable genes, introduction of the identified DNA into the host, and maintenance of introduced DNA in the host and transfer to its progeny. Statement II: Recombinant DNA technology can be accomplished without restriction enzymes if DNA ligase alone is used on foreign DNA. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Statement I is correct but Statement II is incorrect.
