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.
Viruses are obligate intracellular parasites, which means they have to live inside of a host and steal hosts enzymes to allow replication, like when aliens inhabit the bodies of politicians and run for officeâ¦ it happens.hat being said, some viruses, including influenza, enter and replicate in the nucleus because they require splicing enzymes for replication. Virus replication usually occurs in two stages: early and late. These two stages are defined by the types of viral proteins made in each stage.
