stage are markedly prolonged, which is probably associated with the 

 intrinsically slower division rate of natural microbial hosts. 



In principle, the development of rapid DNA sequencing 

 techniques permits the determination of the entire genome of the 

 free-living phages. A complete sequence of a phage will provide 

 information on promoter sequences, termination signals, and 

 ribosome binding sites of the phage, and, by extension, the host 

 DNA.
