Bacteriophage f1 is closely related to Phage M13
The full sequence is available from NCBI at GenBank: J02448.1
Phage f1, a ssRNA phage, should not be confused with phage F1, a ssDNA phage, but f1 may also refer to a ssDNA phage.
Morphology
Phage f1 is a filamentous (rod-shaped) ssDNA phage. [1] The rods are about 8500 Å long, with a weight average molecular weight of 1.1x107. Depending on the staining technique, the rods appear to be 43 or 63 Å wide [1] , but are accepted to be about 60 Å [2].
Genome Organization
6407 bp of ss-DNA, circular
10 genes encoded; generally referred to by Roman numerals I-X as listed on the f1 Gene page.
Life cycle
Adsorption and Injection
f1 is male specific; it only infects Hfr or F+ strains of E. coli. [1]
DNA replication
Packaging
Lysis
