Viruses and their way of entering the host cell

A viral infection begins when the genome of the virus enters the host cell. Once it's inside, the viral genome commandeers the host, it reprograms the cell to copy viral nucleic acid and manufacture proteins from the viral genome. The nucleic acid molecules and capsomeres self-assemble into viral particles and exit the cell. Viruses were discovered by researching the cause of tobacco mosaic disease. viruses have viral envelopes cloaking their capsids these envelopes are derived from the membrane of the host cell. The most complex capsids are found in viruses that infect bacteria, these are called bacteriophage or phages. Viruses are infectious particles consisting of nucleic acid ina protein coat or membranous envelope. Some
