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 order to produce new copies of itself, a virus must use the host cell's reproductive machinery.. The newly made viruses then leave the host cell, sometimes killing it in the process, and proceed to infect other cells within the organism.he second pathway available to viruses is called the lytic cycle. In the lytic cycle, the virus first attaches itself to the surface of the host cell. It then makes a hole in the cell membrane and injects its genetic material (DNA or RNA).
