Target-primed reverse transcription

WebNov 21, 2006 · This process is referred to as target-primed reverse transcription (TPRT) . After reverse transcription, the second (top) DNA strand is cleaved by the second protein subunit, which binds a different DNA sequence downstream of the insertion site ( 9 ). WebJun 5, 2012 · This serves as the primer for DNA synthesis by reverse transcriptase (2). The first sequences to be copied are the unique sequence at the 5′ end of the RNA (U5, red) and a short repeat sequence (R, green) present at both ends of the RNA.

WebLTR transposition generates a free cDNA within a virus like particle in the cytoplasm. This cDNA is then inserted into the target in the nucleus. When a nonLTR element transposes, an RNA copy of the element associates with the target in the nucleus and is used to as a template for target primed reverse transcription.
