title: Inverted repetition in the chromosome of pseudorabies virus.
abstract: An electron microscope examination of pseudorabies virus DNA single strands after self-annealing shows a loop of single-stranded DNA at one end of the molecule contiguous to a double-strand region. The molecule then terminates in a further single-stranded region that does not form a loop. It is suggested that the DNA contains a sequence of 13.3 x 106 daltons at one end, which is repeated internally with opposite polarity. The segment of the genome separating the repeats has a double-strand molecular weight of 5.4 x 106. The whole native DNA has a molecular weight of 90 x 106 to 95 x 106.
