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 endocytosis, the virus tricks the host cell by attaching to surface molecules, usually receptors that bind molecules essential to the cell's function, and are then passively carried into the cell. With both methods, the virus is able to penetrate the cell's membrane and enter the cell.t then injects its nucleic acid (DNA/RNA) int â¦ o the host to replace the host's genetic material. This is a step in the lytic cycle, see the related question below for more details of this entire viral replication process. More: Enveloped and non-enveloped viruses enter a host cell in two ways.
