The genomic structure of REV. (A) – REV-A strain, (B) – “defective” REV-T strain. LTR – long terminal repeats, U3 and U5 – unique regions, gag – gene encoding viral structural protein, pol – RNA-dependent DNA polymerase and DNA integrase, v-rel – oncogene present only in the defective REV-T strain, β – one thousand base pairs
