Question

Site directed mutagenesis facilitated research on

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Fats

Hint:

Site-directed mutagenesis is a powerful technique for studying protein function by introducing specific mutations in the DNA sequence encoding the protein.

Answer 1

The Correct Option is B

Step 1: Understanding site-directed mutagenesis.
Site-directed mutagenesis is a method used to introduce specific mutations into a DNA sequence, allowing researchers to study the function of specific amino acids in proteins. This technique has facilitated extensive research in protein structure and function.
Step 2: Analyzing the options.
(1) Carbohydrates: Site-directed mutagenesis is not typically used for studying carbohydrates, as it is more suited to altering DNA that encodes proteins.
(2) Proteins: Correct — Site-directed mutagenesis is most commonly used to study proteins by altering specific amino acids and analyzing their effect on protein function.
(3) Lipids: Site-directed mutagenesis is not typically applied to lipids, as they do not have a DNA sequence to be altered.
(4) Fats: Like lipids, fats are not targeted by site-directed mutagenesis, which focuses on DNA and protein research.
Step 3: Conclusion.
The correct answer is (2) Proteins, as site-directed mutagenesis is used to study proteins by introducing specific mutations in their encoding genes.
