Isi dengan Judul Halaman Terkait OBJECTIVES After studying virus and its roles, the students are able to understand how virus live and discuss the prevention of its attack. Hal.: 2 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Virus and The Role The history of virus discovery Adolf Meyer ( Jerman, 1883) investigated pests in healthy tobacco which has yellow spot Dmitri Ivanowsky( 1983) filtered the extract of tobacco leaf having yellow pests and infected it to healthy tobacco plant and it was infected. It can be cncluded that the cause of this pest is because the size of it is smaller than that of bacteria so that it can slip out from the filter. Martinus W. Beijerinck( Belanda,1897) stated that yelow pest causing agents can breed in creatures. Wendelly Stanley(Amerika, 1935) named tobacco mosaic virus (TMV) which means poison.

Characteristics and Natures of Virus The size is 10 up to 400 nm (0,1-0,4um) and can be observed by e electron microscope. It is not composed by cells. Having one nucleate acids (DNA/RNA). All virus have compound of nucleate acids (DNA or RNA). It is as transitional creatures. It can be regarded as a thing because it can be crystallized. Having wrappers of nucleate acid (kapsomer) It is as obligate parasite. Hal.: 4 Isi dengan Judul Halaman Terkait
