There are over 200 different HPV genotypes identified to date and each displays a strict tissue specificity for infection. The HSV genome is large (152 kbp) and structurally complex, consisting of two unique regions (UL and US) flanked by inverted repeat sequences arranged as ab-UL-b′a′c′-US-ca (reviewed in Ward and Weller 2011, and references therein).The HSV genome contains three origins of replication: OriS is present twice in the viral genome in the repeated … acid either DNA or RNA, New alternative to studying viruses besides, Enders, Weller and Robbins developed cell culture, One-step growth curves used to study a single, Developed by Delbruck to study E. coli T4, Proteins, glyoproteins, carbohydrates, lipids, Enveloped virus entry vs. naked virus entry, 3. Replication: The replication process of DNA viruses differs from that of RNA viruses. Although the replicative life cycle of viruses differs greatly between species and category of virus, there are six basic stages that are essential for viral replication. - ... 80 200 nm (diameter) 20 nm 50 nm 50 nm 50 nm (a) Tobacco mosaic virus (b) Adenoviruses (c) Influenza viruses (d) Bacteriophage T4 (a) ... - Virus Notes Ch. Viral Replication: Basic Concepts • Viruses are obligate intracellular parasites • Viruses carry their genome (RNA or DNA) and sometimes functional proteins required for early steps in replication cycle • Viruses depend on host cell machinery to complete replication cycle and must commandeer •Nonenveloped viruses exhibit full maturation in the cytoplasm or nucleus with disintegration of cell.

The protein capsid is stripped away from the genome, and the genome is freed in the cell cytoplasm. However, in some DNA viruses the replication takes place in cytoplasm (e.g., poxviruses) and in some others in the nucleus of host (e.g., parvoviruses, papovaviruses, adenoviruses, herpes viruses).
