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.
DNA replication is the action of DNA polymerases synthesizing a DNA strand complementary to the original template strand. To synthesize DNA, the double-stranded DNA is unwound by DNA helicases ahead of polymerases, forming a replication fork containing two single-stranded templates.Replication processes permit the copying of a single DNA double helix into two DNA helices, which are divided into the daughter cells at mitosis.nitiation of eukaryotic DNA replication is the first stage of DNA synthesis where the DNA double helix is unwound and an initial priming event by DNA polymerase Î± occurs on the leading strand. The priming event on the lagging strand establishes a replication fork.
