Arising Biological Questions About Genomic Signatures
Are genomic signatures relevant for pathogen replication?
Silencing of host genes. MHC?
Competitive advantage over other viral serotypes
Role in virus recombination and the generation of new variability
Are some genomic signatures duplications defining host range and are related with vector transmission?

Process Flow
a. The authorization process begins from the client and is passed to the Security and Administration API . This process select the services API.
b. The Administration selects the Data Analysis API and the data request is passed to the Data Abstraction Layer (DAL).
c. The data mapping function is invoked, the specified application and URI are referenced and the proper driver.
d. The various data drivers implement the Metadatabse layer (MDL) produce common requests and result sets are selectively cached in the Data Abstraction Server.
e. Once data is delivered from one of the database, it may be sent to the analysis application.

A comprehensive genomic analysis of the genus Flavivirus genus suggest the existence of a core viral genome composed by 47 elements each with a length of 12 aminoacids. For 7 of the viral genomes there is at least one copy of each element. However, several genomic signatures are duplicated up to three times. But it remains unclear if the generation of genomic signatures are cyclic events.
Our analysis shown that duplication of genomic signatures and the mutation still a relevant process in viral genome evolution, and could be is involved in viral recombination and self interaction.
As mutation pressures selected fitted individuals, new species with novel characteristics emerged. However, there is a tradeoff between viral pathogenesis and dispersal.

Each of these particles is about 4.5 microns long--about one-twentieth the diameter of a human hair, which is about 100 microns. Alternating gold and silver stripes create the "barcode" pattern on these tiny particles. When viewed in blue light under a microscope, silver is much more reflective than gold, making different-patterned particles easy to identify.
