NEET Zoology Genetic Engineering Assertion Reason Question
Assertion (A): In genetic engineering, the origin of replication is crucial for the replication of foreign DNA within a host cell.
Reason (R): The origin of replication in a cloning vector is responsible for inactivation of the gene where recombinant DNA is inserted.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The origin of replication initiates DNA replication within a host cell, but it is not responsible for inactivation of the gene. Inactivation can occur due to insertional inactivation, where the insertion of foreign DNA disrupts the coding sequence of a gene.
