The prolate structure of a typical head on a bacteriophage. An elongated icosahedron is a common shape for the heads of bacteriophages. Such a structure is composed of a cylinder with a cap at either end. The cylinder is composed of 10 elongated triangular faces.
The universal structure of antibody includes the constant regions part of the fragment crystallizable(Fc) region of the antibody (shown in dark blue). It also includes the fragment antigen binding which is composed of one heavy and one light chain (shown as L for light and H for heavy).
Hemagglutinin, neuraminidase, and M2 protein in the influenza virus; gp160, composed of subunits gp120 and gp41, in the human immunodeficiency virus (HIV). [1] Viral glycoproteins play a critical role in virus-to-cell fusion. Virus-to-cell fusion is initiated when viral glycoproteins bind to cellular receptors. [5]
Life-cycle of a typical virus (left to right); following infection of a cell by a single virus, hundreds of offspring are released. When a virus infects a cell, the virus forces it to make thousands more viruses.
