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.
The typical way in which a virus replicates is by first attaching to a host cell, penetrating the host cell, releasing the viral genomic nucleic acid inside the host cell and replicating by synthesizing the viral RNA, and assembling and synthesizing viral protein. That was a brief look at the structure of a virus.hether a virus is a proper life form or organism is a topic of much debate. There are several reasons behind such contradictory opinions. Although viruses have genes and undergo evolution by natural selection, they do not reproduce by cell division as they do not possess a cellular structure.
