PPT-Virus structure Introduction to virus structure

Outside their host cells viruses survive as virus particles also known as virions The virion is a gene delivery system it contains the virus genome and its functions are to protect the genome and to aid its .

General description. Viruses is not living organism, as they lack two essential properties of life- they cannot . replicate. independently, and cannot . survive. long –term independently so it is obligate intracellular organism ..
