The UnaL2 LINE 3′ element is an RNA element found in the UnaL2 LINE (long interspersed nuclear element) and partner SINE (short interspersed nuclear element) from eel. This conserved element is a stem-loop that is critical for their retrotransposition found in their 3′ end.
The UnaL2 LINE 3′ element is a fundamental RNA structural component discovered within the UnaL2 LINE and SINE elements of eel. This critical element, situated at the 3′ terminus, facilitates the retrotransposition process through its stem-loop configuration.
