Answer:
DNA transposons
Explanation:
Transposons are DNA sequences that move from one place of the genome to another, they are also known as jumping genes. There are two types of them, the first type are the ones called retrotransposons and the second type are the ones called DNA transposons.
Retrotransposons requiere reverse transcription to form the DNA sequence (they need the help of RNA) while DNA transposons are segments of DNA that exert and insert themselves in the DNA sequence by a mechanism called cut and paste.
