119 virus adhering at host cell until make new virus trough lytic or lisogenic. Second meeting • The role of virus in our life Virus can give benefit for human, like as a vector in genetic engineering. Virus can give negative effects for human diseases like Avian influenza, AIDS, hepatitis, Tobacco Mosaic Virus TMV in tobacco plants, New Castle Disease ND in hen, etc. • Finding information about the role of virus for our live trough book virtual laboratory . • Done experiment about the benefit role of virus by virtual laboratory. • Approve virus can not live free in nature, it must exist in other organism. • Explain the role of virus to our live. • Predict hypothesis by experiment. • Observe the ways in ovo virus cultivation in the virtual laboratory . • Make conclusion from observation with virtual laboratory . sheet, questions test. 2 x 45’ Wonogiri, July 2010 Teacher ……..................................
