Which of the following is a non-autonomous retrotransposon?
Show answer and explanation
Correct answer: SINEs (Short Interspersed Nuclear Elements)
SINEs (Short Interspersed Nuclear Elements) are non-autonomous because they lack the reverse transcriptase gene needed for transposition. They rely on LINE-encoded proteins to mobilize. Alu elements are the most abundant SINEs in the human genome.
