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.
For a virus to reproduce it must infect a host cell. To do this it must first come in contact with the host organism and enter the host organism. Exposure of the host to the virus is the first step in the viral life cycle. Viruses can enter a host in several ways.For example, through a cut in the skin, a mosquito bite (inoculation), or by direct contact with mucus membranes.n the lytic cycle, the genome remains in the cytoplasm. In the lysogenic cycle the genome enters the nucleus and inserts into the host genome. In both cases the virus is dependent on the host replication machinery to make viral proteins and genome (new virions).
