Q. Consider the following statements regarding Recombinant DNA (rDNA) technology:
1.Recombinant DNA is a molecule created in vitro by combining DNA segments from different biological sources.
2.It involves isolating a target gene, inserting it into a vector, transferring this new DNA into a host organism and cloning it.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C
Notes:

Explanation:

  • Statement 1 is correct: Recombinant DNA technology specifically involves combining DNA from different sources to modify genetic makeup.
  • Statement 2 is correct: It involves isolating a target gene, inserting it into a vector (like a plasmid or virus), transferring this new DNA into a host organism (bacteria/yeast), and cloning it. The technology alters the genome of an organism by adding new genes, deleting, or editing existing genes to produce desirable traits (e.g., insulin production, drought-resistant crops).
