Annuum the common pepper of garden occurring many varieties. Kanamaru S. Some phages have mutated their DNA over time to rid it of restriction sites though bacteria evolved quite wide range enzymes. It is composed of proteinaceous subunits called capsomeres. Kunisawa T

With the help of viral lysozyme which digests tough peptidoglycan layer in bacterial cell wall middle between outer and inner membranes this punctures . IcosahedralAn icosahedron is polygon with vertices and faces. The initiator complex forms one vertex of head be called portal as DNA will enter capsid through . These enzymes recognise specific short codes in viral DNA restriction sites and cut at points. This a small protein of residues

When the viral particle has entered host cell cellular enzymes digest capsid and its constituent capsomeres thereby exposing naked genetic material DNA RNA of virus which subsequently enters replication cycle. This group comprises all those viruses which do not fit into either of above two groups. Sometimes the different frames may be read in same direction . This may be especially important as the genome low in base pairs at

Dallwitz M. T proteins gp and trimers of wac whisker or fibritin which forms the whiskers bind portal vertex to complete head then binds assembled tail. Some viruses overcome this by utilising an enzyme incorporated into their tail digest carbohydrate chains of slime and dissolve way through leading bacteria modifying chemical makeup carbohydrates render ineffective. Sander Established . Those with short heads will lack the entire genome and so cannot infect complete replication alone but may do host which is superinfected by more than phage of phages having missing genes

Simultaneously the tail sheath contracts below as wave of contraction travels along its length presumably from bottom top and inner tailtube with needlelike tip penetrates target cell envelope help lysozyme injecting DNA into host. Some phages have unusual bases in their genetic code to prevent recognition by restriction enzymes
