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.
HIV-1 reverse transcriptase is one of the key players in the mechanism of infection by this retrovirus. The HIV-1 reverse transcriptase enzyme is responsible for copying a single-stranded viral RNA genome into double-stranded DNA (Sarafianos et al, 2001). The newly created DNA can then be incorporated into the host genome; the host is mainly the human in the case of HIV. The HIV-1 reverse transcriptase enzyme contains two main domains: a DNA polymerase domain and a ribonuclease H (RNase H) domain. The DNA polymerase is able to copy either an RNA or DNA template.
