Human poliovirus, molecular model 插畫檔

Human poliovirus particle. Molecular model of the capsid of the human poliovirus. The capsid is a protein coat that encloses the virus's genetic information (genome), stored as RNA (ribonucleic acid). The protruding proteins are receptors, which enable the virus to recognise and bind to a host cell. Poliovirus infects children and causes poliomyelitis, a disease which in severe cases damages the nervous system, leading to paralysis or death.
