  • Hepatitis B Virus Conclusion

    The core of the hepatitis B virus is generally in the shape of an icosahedron. Within the virus, there are two strands of DNA, one smaller than the other, which is circular.

Eventually, the host cell bursts and dies, releasing the new viruses, which go on to again reproduce in this fashion. This is why viruses spread so quickly, because they are so effective at replicating themselves. The viruses can only attach to a cell that will support the replication, and for HBV,…
