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 the lytic cycle, which is considered the main cycle in viral replication, once the viral DNA enters the cell it transcribes itself into the host cell's messenger RNAs and uses them to direct the ribosomes. The host cell's DNA is destroyed and the virus takes over the cell's metabolic activities.
