Question

Which one of these statement about the applications of gene cloning is false?

• A. Large amounts recombinant protein can be produced by gene cloning
• B. $\text{DNA}$ fingerprinting is used to detect proteins bound to $\text{DNA}$
• C. Cloned genes can be used to detect carrier of disease-causing genes
• D. Gene therapy attempts to correct a disorder by delivering a good copy of a gene to a patient

Answer 1

The correct option is B $\text{DNA}$ fingerprinting is used to detect proteins bound to $\text{DNA}$

$\text{DNA}$ fingerprinting is a term that defines a collection of methods to analyze protein– $\text{DNA}$ complexes and to identify the position of the binding site. When a protein binds to a specific site on a $\text{DNA}$ sequence, fingerprinting helps to identify where the binding site is. In addition, it can also give some clues on the specificity of the binding and on the structure of the protein–$\text{DNA}$complex.

So, the correct answer is option 'b'.
