Head and tail virus shape
WebThe shapes of virus particles or viruses are known chiefly from electron micrographs. The viruses may be spherical, rod like, brick-shaped B or shaped like a tadpole with a head and slender tail (D). On the basis of the shapes of the viruses, the plant viruses chiefly fall under the following three categories: WebThe head of phage T 4 has a diameter of 65 nm and is 100 nm long. 2. Tail: The tail is cylindrical and is composed of a central hollow core or tube (7 nm thick) surrounded by a contractile sheath (protein) and a terminal base plate with tail fibres (usually six in number). Each corner of base plate contains a short pin or spike and a 130 nm ...
