Hairpin loop structure at the termini of the chlorella virus PBCV-1 genome.
The termini of the chlorella virus PBCV-1 330-kb dsDNA genome consist of 35-nucleotide-long, incompletely base-paired, covalently closed hairpin loops that exist in one of two forms. The two forms are complementary when the 35 nucleotide sequences are inverted with respect to one another (flip and flop). Each hairpin loop structure is followed by an identical 2221-bp inverted repeat sequence after which the DNA sequence diverges. The strategy for cloning the PBCV-1 DNA hairpin ends may be useful for cloning other hairpin termini.
