Final answer:
Retroviral-like transposons contain genes such as Gag, RT, Prt, and Int that encode proteins involved in the transposition process.
Step-by-step explanation:
Retroviral-like transposons contain several genes, including the Gag gene which encodes the group-specific antigen (Gag protein), the RT gene which encodes the reverse transcriptase enzyme, the Prt gene which encodes a protease enzyme, and the Int gene which encodes the integrase enzyme.
These proteins play important roles in the transposition process of retroviral-like transposons. The Gag protein forms virus-like particles that encapsulate the transposon RNA, the reverse transcriptase enzyme makes copies of the transposon RNA, the protease enzyme breaks down the virus-like particle, and the integrase enzyme helps integrate the transposon into the host genome.
