- DNA Replication
- DNA Transposon
- DNA Hybridisation
- DNA Recombination
Show Solution
Verified By Collegedunia
The Correct Option is B
Approach Solution - 1
Transposons, or "jumping genes", are DNA segments that can move from one position to another within the genome. They play roles in gene mutation, genetic variation, and genome evolution.

Elimination of terms:
DNA Replication refers to copying the entire genome, not a segment moving between locations, so it is ruled out.
DNA Hybridisation refers to base-pairing between complementary strands (often from different sources in a lab setting), unrelated to movement within a chromosome.
DNA Recombination involves exchange of genetic material between DNA molecules, typically during processes like crossing over, again distinct from a mobile element relocating itself.
By elimination, the term describing a mobile DNA segment capable of moving from one chromosomal location to another is the DNA Transposon.
