Computer Viruses as Artificial Life
There has been considerable interest in computer viruses since they first appeared in 1981, and especially in the past few years as they have reached epidemic numbers in many personal computer environments. Viruses have been written about as a security problem, as a social problem, and as a possible means of performing useful tasks in a distributed computing environment. However, only recently ...

The development of molecular biology in the second half of the century showed that viruses are strict molecular parasites of cells, putting an end to previous virocentric debates that gave viruse...
متن کاملLife cycle of RNA oncogenic viruses.
In view of the increasing evidence suggesting that human Cancer cells contain molecular footprints related to murine and primate type-C RNA tumor viruses (1-7), it is appropriate in this symposium to discuss a simple scheme for the life cycle of RNA tumor viruses. It is hoped that this scheme will be useful in searching for virus related proteins, nucleic acids and particulates in human leukemi...
متن کاملUnusual life style of giant chlorella viruses.
Paramecium bursaria chlorella virus (PBCV-1) is the prototype of a family of large, icosahedral, plaque-forming, dsDNA viruses that replicate in certain unicellular, eukaryotic chlorella-like green algae. Its 330-kb genome contains approximately 373 protein-encoding genes and 11 tRNA genes. The predicted gene products of approximately 50% of these genes resemble proteins of known function, incl...
