Virus
- What is a virus?
- A virus is a non-celular parasite that only can reproduce
by invading the cell of other living things
- A virus is a non-celular parasite that only can reproduce
by invading the cell of other living things
- The structure of viruses
- Viruses consist of a stand of nucleic acid, (genetic material which can be
DNA or RNA) surrounded by a protective protein coat calleda capsid.
- Some viruses, such as influenza, have a further membrane envelope of
lipid, surrounding the protein. Other viruses also have a tail
- Viruses consist of a stand of nucleic acid, (genetic material which can be
DNA or RNA) surrounded by a protective protein coat calleda capsid.
- Life processes of
viruses
- As they do not feed, they are considered obligate parasites and, in order to
reproduce, they insert their genetic material in the cells of living organisms.
- Viruses only have the life process of
reproduction.

reproduction.
- As they do not feed, they are considered obligate parasites and, in order to
reproduce, they insert their genetic material in the cells of living organisms.
- Reproduction of
viruses
- The virus attaches itself to the cell membrane. The whole
virus or just its genetic material is injected into the cell.
- The host cell follows the instructions from the genetic material of the virus
and replicates the nucleic acids and produces the capsid and tail proteins.
- All of the components are put together and a new virus is created and
released. This can destroy the host cell.
