The Hepatitis B Virus Capsid (IMAGE) Indiana University Caption This image shows the shell, or capsid, that encapsulates the DNA of the hepatitis B virus, which is composed of 240 copies of the same protein. The green areas depict the structurally unique regions, which are found in a repeated arrangement across the surface of the shell. The small red areas reveal the sites where the molecule HAP binds to the virus.
