On April 19, 2011, Map Maker was added to the American version of Google Maps, allowing any viewer to edit and add changes to Google Maps. This provides Google with local map updates almost in real time instead waiting for digital map data companies to release more infrequent updates. 2012
The basic process of viral infection and virus replication occurs in 6 main steps. 1  Adsorption-virus binds to the host cell. 2  Penetration-virus injects its genome into host cell. 3  Viral Genome Replication-viral genome replicates using the host's cellular machinery.
In general, virus need its host to propagate (replicate may be right, reproduce may not). Virus infect the host cells, insert its genetic material (can be RNA or DNA), integrate them into the host genome for the production of viral proteins and its own genetic material. They packages in the cytoplasm and leave the host.eplication of Viruses. A virus replicates [the term often heard in place of reproduces] inside a host cell with the process called the Lytic Cycle. The details of the steps of the Lytic Cycle are in the related questions below in the Related Questions section.
