Structure of phage phi X 174 capsid
Phi X 174
Virus classification
Group: Group II (ssDNA)
Family: Microviridae
Genus: Microvirus
Species: phi X 174 phage

The phi X 174 (or phi X) bacteriophage was the first DNA-based genome to be sequenced. This work was completed by Fred Sanger and his team in 1977.[1] In 1962, Walter Fiers had already demonstrated the physical, covalently closed circularity of phi X 174 DNA.[2]

This phage has a very small amount of DNA. Phi X has 11 genes in 5386 bases (it is single stranded) in a circular topology; several of these genes express similar function in two groups. The GC-content is 44% and 95% of nucleotides are coding genes.

In 2003, it was reported that the whole genome of phi X 174 had been assembled synthetically from scratch.[3]
