Question

Insertion of recombinant DNA within the gene encoding for β–galactosidase leads to ________

• A. amplification
• B. transformation
• C. insertional inactivation
• D. cloning

Answer 1

Answer:

C. insertional inactivation

• Insertional inactivation is the process in which the gene is inactivated due to the insertion of other genes within it or within its coding sequence.

• This leads to loss of function of that specific gene.

• Thus, insertion of recombinant DNA within the gene encoding for β–galactosidase will lead to insertional inactivation.
