WebThe long terminal repeats (LTRs) are indicated by the green boxes. The arrows over the boxes indicate open reading frames, whereas the shaded regions of the boxes show portions of the genes where there is strong conservation of amino acid sequence between the different retrotransposons and retroviruses. RB, ... WebOnce released into the cytoplasm, viral RNA is transcribed into double stranded linear DNA flanked directly by long terminal repeats (LTRs). The DNA is transported into the nucleus within the pre-integration complex. In the nucleus the linear un-integrated DNA is either inserted into the host genome or circularised [6,7,8].
