questions: 1 Discuss the two methods of viral replication. The two methods of viral replication are done in animal viruses. The first method deals with DNA viruses and the second is RNA viruses. In the DNA virus‚ the viral DNA enters the nucleus of the host cell. Than it is transcribed into mRNA and leaves the nucleus into the cytoplasm. The early mRNA then translates into early viral proteins. The early viral proteins deal with the replication of viral DNA‚ they are then transported back into the nucleus

target host cell. Upon binding to the host cell membrane via teams of glycoproteins‚ the virion is then phagocytosed. Soon the nucleus is seized and all regular host cell mechanisms are shut off. Replication of HSV-1 is specific encoding immediate early‚ early and late genes. Once the virus replication process is complete the virus exits epithelial cells near the site of infection through a process known as cell lysis. Sensory neurons are the specific target of HSV-1‚ where it can then travel to

the properties and uses of plasmids in G.M. experimentation. Plasmids are extrachromosomal genetic elements found in a variety of bacterial species. They are double stranded; autonomously replicating‚ supercoiled‚ covalently closed circular (ccc) DNA molecules that range in size from 1 kb to greater than 200 kb. Often‚ plasmids contain genes coding for enzymes that‚ under certain circumstances‚ are advantageous to the bacterial host (Table 1). Table 1. Some of the phenotypes conferred by different
