The dengue virus has a roughly spherical shape. Inside the virus is the nucleocapsid, which is made of the viral genome and C proteins. The nucleocapsid is surrounded by a membrane called the ...

Now, researchers used cryoelectron microscopy (cryo-EM) to elucidate the structure ... is published in Cell in the paper, “Structural and functional analysis of the Nipah virus polymerase ...

which infect more cells. The spread of the dengue virus results in viremia, which is a high level of the virus in the bloodstream. To fight the infection, the immune system produces antibodies to ...

Later, the structure ... cell’s machinery to produce viral proteins and genetic material to make new copies of themselves. Viruses with an envelope steal a fatty layer from the cell. Then, new ...
