Which organism is commonly used in genetic engineering?
Which organism is commonly used in genetic engineering?
Show Hint
Bacteria are like biological "factories." Once you give them the DNA instructions, they can produce massive amounts of medicine or protein in a very short time.

Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Genetic engineering involves manipulating the DNA of an organism to introduce new traits. Scientists prefer organisms that reproduce quickly and have simple genetic structures.
Step 2: Detailed Explanation:
Bacteria (especially \textit{E. coli}) are widely used because they grow rapidly, their genome is well-understood, and they contain plasmids (circular DNA) that can be easily manipulated to carry foreign genes, such as the gene for human insulin.
Step 3: Final Answer:
The correct option is (b).
