The over-all homology between sequences is shown as a straight line on the diagonal, while regions of repeats are shown as lots of lines in the same region, allowing visualization of where the repeated regions are between sequences. Panel A, Nucleotide sequence homology between human herpesvirus-4, (HHV-4) EBNA1 and human herpesvirus-8 (HHV-8) LANA1; Panel B, (Papiine herpesvirus-1, HV-1) baboon EBNA1; Panel C, (Macacine HV-4) rhesus EBNA1; Panel D, (Alcelaphine HV-1) ORF73; Panel E, (Ovine HV-2) ORF73, and; Panel F, (Samirine HV-2) ORF73. In each panel the intensity of the dot plots indicate the level of homology between the sequences being compared. Transcript sizes are shown in kb on both axes. The Genbank accessions numbers for these sequences are listed in the Materials and Methods.
