Final answer:
SINES code for reverse transcriptase is true.
Step-by-step explanation:
A SINE retrotransposon is a type of non-LTR retrotransposon that lacks genes but is flanked by 5' and 3' UTRs. It relies on the activity of a non-LTR transposon (a LINE) to carry out the enzymatic activities required for transposition. The reverse transcriptase enzyme plays a crucial role in the SINE retrotransposition process by generating a cDNA copy of the transposable element. Therefore, the statement that SINES code for reverse transcriptase is true.
