Question

A process by which the genetic information of organism is changed is

• A. \( \text{Mutation} \)
• B. \( \text{DNA replication} \)
• C. \( \text{Gene resistance} \)
• D. \( \text{Mutagenesis} \)

Hint:

In biotechnology, site-directed mutagenesis is a key technique used to study protein functions by changing specific DNA sequences.

Answer 1

The Correct Option is D

Concept: Alterations in the genetic sequence can occur naturally or be induced through experimental means.
• Mutation refers to the actual change or resulting variation in the DNA sequence.
• Mutagenesis refers to the functional process of generating such changes.

Step 1: Distinguishing between result and process.
While a "mutation" is the specific event or outcome, the question asks for the "process." Mutagenesis is the biological or laboratory process that leads to a permanent change in the genetic information.

Step 2: Types of Mutagenesis.
It can be spontaneous (occurring naturally due to replication errors). It can also be induced (using physical or chemical agents known as mutagens).
