摘要：

The nature of viruses and the fundamental difference between their reproduction mechanism and cell division are discussed. The ways for storage and expression of genetic information in viruses are considerably more diverse than in cells. It is widely accepted nowadays that the "RNA world" appeared earlier than the "DNA world." Hypotheses of the origin of viruses are discussed in conjunction with these theories (a hypothesis that cells with a RNA-genome appeared first, and were followed by viruses, and a hypothesis according to which RNA-containing viruses appeared first). It is suggested in both cases that the DNA-genomes first appeared
