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.
A virus has proteins (called protein markers) on its coating (capsid), which allows the virus to attach itself to the host cell.It 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.The capsid or viral envelope can fuse with the host cell membrane and release the viral material into the host cell, or the virus can trick the host cell.ore: Enveloped and non-enveloped viruses enter a host cell in two ways.
