Transposable Genetic Elements · Zoology

Which feature is common to most transposable elements?

  1. Genes for metabolic enzymes
  2. Ability to replicate independently
  3. Terminal repeat sequences
  4. Double-stranded RNA genome
Show answer and explanation

Correct answer: Terminal repeat sequences

Most transposable elements possess terminal repeat sequences (inverted or direct) at their ends. These sequences serve as recognition sites for transposase or integrase and are required for the transposition reaction.
