we conclude on the basis of these studies that ( i ) sequences from the right end of standard virus dna contain a recognition signal for the cleavage and packaging of concatemeric viral dna , ( ii ) the sequence-specific cleavage is either a prerequisite for or occurs during the entry of viral dna into capsid structures , and ( iii ) dna molecules significantly shorter than full-length standard viral dna can become encapsidated within nuclear capsids provided they contain the cleavage/packaging signal .
