Answer:
Transposon is a fragment or sequence of DNA that can move unregulated to any point in the cell genome, leading to a phenomenon called transposition.
Step-by-step explanation:
Transposon is the name of what was previously known as jumping genes, being a DNA sequence capable of moving freely within a DNA molecule. A transposon can produce mutations by translocation, altering the total amount of nucleotide in DNA molecule.
Genetic changes that are linked to evolutionary processes can be due to the existence of transposons, since they can even induce chromosomal changes.
