Question

Protein engineering is used to study the proteins to compare the catalytic properties of

• A. Normal and mutated form of enzyme
• B. Normal form of enzyme
• C. Mutated form of enzyme
• D. Normal and mutated form of proteins

Answer 1

The correct option is A Normal and mutated form of enzyme

Protein engineering is use of sophisticated techniques to produce mutant proteins with novel properties of value to be created. These mutant proteins may have only minor changes and are then compared with normal proteins/wild type proteins. For example site-directed mutagenesis introduces an amino acid at a specified location in target gene thereby altering the translated enzyme. Correct answer is A. Proteins with catalytic properties are called enzymes which makes option D wrong.
