H1N1 flu virus particles. Computer artwork of two H1N1 influenza (flu) A virus particles (virions). At the virus' core is the RNA (ribonucleic acid) genetic material (centre in cut-away virus at left). This is surrounded by a nucleocapsid (middle layer) and a lipid envelope (outer layer). In the envelope are two types of protein spike,haemagglutinin (H,tri-lobed spike) and neuraminidase (N,square),which determine the strain of virus. These are used for recognising and binding to the host cell | |
