Final answer:
In Biology, sequences within the transposon between the inverted terminal repeats encode the necessary enzymes for transposition.
Step-by-step explanation:
The subject of this question is Biology. The question is asking about what is encoded by sequences within the transposon between the inverted terminal repeats.
In the case of LINES (Long Interspersed Nuclear Elements), the ORFs (genes) are encoded between the inverted terminal repeats. These ORFs are responsible for encoding enzymes needed for the transposition process.
For example, in the human L1 Line, the second ORF (ORF2) encodes the reverse transcriptase and an integrase activity essential for transposition of the LINE.
