VIRUS:
1:VIRUS ARE NOT CELLS
2:THEY ARE NOT CAPABLE OF INDEPENDENT REPLICATION
3:THE CANNOT SYNTHESIZE THEIR OWN ENERGY AND PROTEINS
4:THE ARE TOO SMALL TOO BE SEEN UNDER THE LIGHT MICROSCOPE
5:STUDY OF VIRUS IS KNOWN AS VIROLOGY
6:FIRST EVIDENCE ABOUT THE EXISTENCE OF VIRUS CAME IN 1884 BY CHARLES CHAMBERLAND
CHARACTERISTICS OF VIRUS:
VIRUS SHOW CHARACTERISTICS OF BOTH LIVING AND NON LIVING THINGS
LIVING CHARACTERISTICS:
1:THEY HAVE THEIR OWN GENETIC MATERIAL IN THE FORM OF DNA OR RNA THAT CAN UNDERGO MUTATION
2:THEY REPRODUCE USING THE METABOLIC MACHINERY OF THE HOST CELL
3:THEY ENTER LIVING ORGANISM AND CAUSE DISEASE
NON LIVING CHARACTERISTICS:
1:THEY DO NOT RESPIRE
2:THEY DON'T HAVE A CELLULAR STRUCTURE
3:THEY CAN BE CRYSTALLISED AND STORED IN THE BOTTLE
SOME VIRAL DISEASES: DISEASES:AIDS,HEPATITIS,HERPES SIMPLEX,POLIOMYELITIS,COTTON LEAF CURL DISEASE ETC
