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.
There are a few basic steps that all infecting viruses follow and these are called the lytic cycle. These include: 1  A virus particle attaches to a host cell. 2  This is called the process of adsorption. 3  The particle injects its DNA or RNA into the host cell called entry. 4  The invading DNA or RNA takes over the cell and recruits the hostâs enzymes.
