Viral replication is the formation of biological viruses during the infection process in the target host cells. The specific phosphorylation of substrate proteins induces activation inactivation or other functional modification and thus determines virus host cell interregulation.
Viral Replication Simplified
Some of the criteria that are required to be fulfilled in order to viral replication are.
Virus replication. The particles are then assembled into the correct structure and the newly formed virions escape from the cell to infect other cells. Virus are the obligate intra cellular particles they replicate inside host cell only. Viral replication is the process by which a virus makes copies of itself.
During the process of viral replication a virus induces a living host cell to synthesize the essential components for the synthesis of new viral particles. 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 that machinery to successfully replicate. Virim uncovered a striking heterogeneity in replication dynamics between cells and revealed extensive coordination between translation and replication of single viral rnas.
After the viral genome has been uncoated transcription or translation of the viral genome is initiated. Here we develop a single molecule imaging assay virus infection real time imaging virim to study translation and replication of individual rna viruses in live cells. It is this stage of viral replication that differs greatly between dna and rna viruses and viruses with opposite nucleic acid polarity.
Replication between viruses is greatly varied and depends on the type of genes involved in them. It can lead to thousands of new viral particles being released into the host s body infecting new cells and leading to the symptoms of disease. The mechanism of protein synthesis shut off varies even within the same viral family.
Through the generation of abundant copies of its genome and packaging these copies the virus continues infecting new hosts. This process culminates in the de novo synthesis of viral proteins and genome. Viruses must first get into the cell before viral replication can occur.
Viral replication is a complex process relying on a network of interacting viral and cellular proteins in which particularly protein kinases play an important regulatory role. Adsorption virus binds to the host cell. Viruses are small and lightweight roughly 1 10th the size of a bacterial cell.
Assembly viral components and enzymes are produced and begin to assemble. The basic process of viral infection and virus replication occurs in 6 main steps. Penetration virus injects its genome into host cell.
Viral genome replication viral genome replicates using the host s cellular machinery. Viral nucleic acid replication virulent viruses either dna and rna shut off cellular protein synthesis and disaggregate cellular polyribosomes favouring a shift to viral synthesis. For a specific virus to replicate within a specific host cell certain condition must be fulfilled.
Most dna viruses assemble in the nucleus while most rna viruses develop solely in cytoplasm.
