Question

Which transposable element uses a “copy-and-paste” mechanism to move within the genome?

• A. DNA transposon
• B. Retrotransposon
• C. Ac-Ds element
• D. Insertion sequence

Hint:

For understanding transposons, remember that retrotransposons rely on reverse transcription to copy their genetic material into new genomic locations.

Answer 1

The Correct Option is B

Retrotransposons move through a “copy-and-paste” mechanism where an RNA intermediate is reverse transcribed and inserted into a new location in the genome.
