This is the double-stranded, covalently closed, circular form of ΦX174 RF I DNA (supercoiled). The molecular weight of ΦX174 RF I is 3.50 x 106 daltons and it is 5,386 base pairs in length. Greater than 90% of the molecules are RF I, and the remainder are RF II, as determined by agarose gel electrophoresis. 

Source:
The ΦX174 RF I DNA is isolated from E. coli HF 4704 infected with ΦX174 am3 cs70 by a modification of the method of Godson and Vapnek (nucleotide sequenced by F. Sanger).
