Transposable Genetic Elements · Zoology

Transposable genetic elements are best defined as DNA sequences that:

  1. Remain fixed at a single chromosomal location
  2. Encode only ribosomal RNA genes
  3. Can move from one genomic location to another
  4. Are found exclusively in viral genomes
Show answer and explanation

Correct answer: Can move from one genomic location to another

Transposable genetic elements are mobile DNA sequences capable of changing their position within the genome — a process called transposition. This movement can disrupt genes or alter regulatory sequences, making TEs a significant source of mutation and genome evolution.
