All the family Myoviridae members share a nonenveloped morphology consisting of a head and a tail separated by a neck. Its genome is linear. The propagation of the virions includes the attaching to a host cell (a bacterium, as Staphylococcus phage G1 is a bacteriophage) and the injection of the double stranded DNA; the host transcribes and translates it to manufacture new particles. To replicate its genetic content requires host cell DNA polymerases and, hence, the process is highly dependent on the cell cycle.[3] The phage contains a genome of 138,715 base pairs with a 30.4% of GC content and 214 predicted genes; this means that the 88.5% of the DNA is coding open reading frames, and therefore the gene density (the number of genes per kilobase) is 1.54.[4] References1. ^{{cite web |url= http://talk.ictvonline.org/files/ictv_documents/m/msl/4090.aspx|title= Master Species List of 2011, version 2|author= International Committee on Taxonomy of Viruses (ICTV) |year= 2011|accessdate=15 October 2012}} {{Taxonbar|from=Q7600420}}{{Virus-stub}}2. ^{{cite journal|pmid=22481600|year=2012|last1=Adams|first1=MJ|last2=Carstens|first2=EB|title=Ratification vote on taxonomic proposals to the International Committee on Taxonomy of Viruses (2012)|volume=157|issue=7|pages=1411–22|doi=10.1007/s00705-012-1299-6|journal=Archives of Virology}} 3. ^{{cite journal|pmid=4329869|year=1971|last1=Baltimore|first1=D|title=Expression of animal virus genomes|volume=35|issue=3|pages=235–41|pmc=378387|journal=Bacteriological Reviews}} 4. ^{{cite journal|pmid=15788529|year=2005|last1=Kwan|first1=T|last2=Liu|first2=J|last3=Dubow|first3=M|last4=Gros|first4=P|last5=Pelletier|first5=J|title=The complete genomes and proteomes of 27 Staphylococcus aureus bacteriophages|volume=102|issue=14|pages=5174–9|doi=10.1073/pnas.0501140102|pmc=556006|journal=Proceedings of the National Academy of Sciences of the United States of America}} 1 : Myoviridae |
