Attachment to the receptor can fore the viral envelope protein to undergo either changes that result in the fusion of viral and cellular membranes, or changes of non-enveloped virus surface proteins that allow the virus to enter. uncoating: A process in which the viral capsid of a virus is removed, leading to the release of the viral genomic nucleic acid.

There are instances, particularly in the streptococci, wherein teichoic acids have been implicated in the adherence of the bacteria to tissue surfaces and are thought to contribute to the pathogenicity of Gram-positive bacteria.

After the virion binds to the surface of a specific host cell, its DNA or RNA is injected into the host cell and viral replication occurs, resulting in the spread of the infection to other host cells.

Several problems exist with current abiogenesis models, including a primordial earth with conditions not inductive to abiogenesis, the lack of a method for simple organic molecules to polymerize, and the mono-chirality of molecules seen in life.

The close relationship between Phylum Bacteroidetes and Phylum Chlorobi are supported by comparative genomic analysis which indicates they are derived from a common ancestor based on unique molecular signatures and common proteins.
