A sample is put on a Virochip microarray, and results are compared to databases of all known viral sequences.
The geometric structures of viruses are beautiful and can be used, along with genomic information, to identify them.
Dengue virus has sophisticated mechanisms for entering a cell, for replicating its RNA genome, and for translating proteins.
Since the 1960s dengue fever has spread to many countries and total case numbers have exploded.
The dengue virus's outer envelope proteins form symmetrical units and overlay the lipid envelope, capsid, and the RNA genome.
Infection begins when the dengue virus uses receptors on an immune cell's surface to gain entry and release its genome.
