Viruses may attack animals and plants. Viruss do non belong to the above 5 lands of life. Archaebacteria also have introns in some genes, an advanced eukaryotic characteristic that was previously unknown among prokaryotes.
Viruses deficiency cellular respiration. Like obligate parasites, they are only capable of reproduction within living cells. Epidemic viruses such as HIV that are passed from individual to individual via sexual junction are unusually similar to computing machine viruses.
In a sense, viruses hijack the host cell and force it to produce more viruses through DNA replication and protein synthesis. If the geologic history of the earth is compared to a hour time scale, the first multicellular organisms do not appear until just after 8: However, they do reproduce, but at the expense of the host cell.
