3' UTR Element
The R2 element 3' UTR RNA is a cis-acting element identified in R2 retrotransposons which is involved in priming the reverse transcription process (an essential part of retrotransposon insertion into the host genome). An RNA fragment found in the R2 3' untranslated region (3'UTR), has been shown to interact with one copy of R2 protein during TPRT. This fragment has been shown to possess conserved secondary structure within Drosophila and silk moths, and also between the two groups.

Famous quotes containing the word element:
“What was any art but an effort to make a sheath, a mould in which to imprison for a moment the shining, elusive element which is life itself—life hurrying past us and running away, too strong to stop, too sweet to lose?”
—Willa Cather (1873–1947)
