title: The termini of the chlorella virus PBCV-1 genome are identical 2.2-kbp inverted repeats.
abstract: The Chlorella virus PBCV-1 genome is a linear nonpermuted 333-kbp dsDNA molecule with covalently closed hairpin termini. The termini (minus the hairpin) are identical inverted repeats of at least 2185 bases after which the sequence diverges. The inverted repeats contain two small potential open reading frames and several direct repeats. However, neither the open reading frames nor the remainder of the inverted repeats are transcribed during PBCV-1 replication. Twenty-nine other Chlorella virus DNAs, of 36 tested, hybridized to the PBCV-1 terminal fragments.
