NEET 2022, Biology Q40: Recombinant DNA Technology

NEET2022Biology
Q.

Transposons can be used during which one of the following ?

  1. A

    Polymerase Chain Reaction

  2. B

    Gene silencing

  3. C

    Autoradiography

  4. D

    Gene sequencing

Solution

Transposons are mobile genetic elements (jumping genes) that can move from one location in the genome to another. Insertion of a transposon into a coding region can disrupt the gene and abolish its expression.

This property is exploited in gene silencing strategies, where transposon insertions are used to identify and inactivate specific genes in functional genomics studies.
