Distinguish between LINE and SINE

Distinguish between LINE and SINE.

Long interspersed nuclear elements (LINEs) and Short Interspersed Nuclear Elements (SINEs) are types of non-coding RNA (ncRNA) elements found in eukaryotic genomes. They are both mobile genetic elements, meaning they can move around within the genome and insert themselves into new locations. However, they differ in their size and structure.

LINEs are typically around 6,000 base pairs in length and contain an open reading frame that codes for reverse transcriptase, an enzyme that allows them to copy themselves into DNA. SINEs are much shorter, usually around 300-500 base pairs in length, and do not contain coding sequences. Instead, they rely on the enzymes encoded by LINEs to replicate themselves. SINEs are thought to be derived from tRNAs or other small RNA molecules and are often found in clusters within the genome.
