The Hepatitis B Virus. The Hepatitis B virus (HBV) is a mostly double-stranded DNA virus in the Hepadnaviridae family. One of five hepatitis viruses, HBV causes acute and chronic hepatitis in humans.he unusually packaged may indicate that the method of replication employed by HBV is not of conserved DNA replication (Garces, HBVP). HBV Genome. Life Cycle: In order to reproduce, the hepatitis B virus, must first attach onto a cell which is capable of supporting its replication.
Diagram of the DNA injection process. Bacteriophages may have a lytic cycle or a lysogenic cycle, and a few viruses are capable of carrying out both. With lytic phages such as the T4 phage, bacterial cells are broken open (lysed) and destroyed after immediate replication of the virion.s the lysogenic cycle allows the host cell to continue to survive and reproduce, the virus is reproduced in all of the cellâs offspring. An example of a bacteriophage known to follow the lysogenic cycle and the lytic cycle is the phage lambda of E. coli.
