a
Sequence categories summarized are from virally derived DNAs and are tallied from sequences depicted in Fig. 5.
b
LTR end of linear vDNA prior to ligation.
c
U, unprocessed LTR end; P, processed LTR end defined as the removal of the CA dinucleotide from the 3′ end via the action of IN; I, incomplete end, defined as an end which was either not completely synthesized or was degraded once synthesized.
