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.
Once the nucleocapsid of this type of virus enters the cell, it proceeds to the nucleus where it mimics the genome of the host cell. Usually, the viral genome is replicated using the host cell DNA polymerase, and the viral genome is transcribed by the host cell RNA polymerase.The resulting transcripts carrying information encoding viral proteins is then transported to the cytoplasm and seen as a template by the host cell ribosomes.iruses 2 A more complex strategy for constructing a virion is used by the majority of animal cell viruses. As above, their genomic DNA or RNA is wrapped in a protein coat. This protein coat:nucleic acid complex (sometimes called a nucleocapsid), is then wrapped in a second outer coat, a lipid membrane.
