here we present evidence to show that two viral dna cleavage and packaging signals reside within a 250 bp subfragment of the terminal repeat , that the termini of mature viral dna are generated by a process involving two separate dna cleavages at sites distal to the cleavage signals , and that the sequences between these two cleavage sites are duplicated by the dna maturation system .
