Virus Replication Process

Penetration of virus into host cell. Viral replication is the process by which a virus makes copies of itself.

A process called adsorption.

Virus replication process. The basic process of viral infection and virus replication occurs in 6 main steps. After the viral genome has been uncoated transcription or translation of the viral genome is initiated. Attachment of virus to outer surface of suitable host cell.

Viral genome replication viral genome replicates using the host s cellular machinery. Some have slow proliferation rates whereas others have fast proliferation rates. Replication between viruses is greatly varied and depends on the type of genes involved in them.

Through the generation of abundant copies of its genome and packaging these copies the virus continues infecting new hosts. 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. It is this stage of viral replication that differs greatly between dna and rna viruses and viruses with opposite nucleic acid polarity.

The duration of replication varies for different viruses. When the virion invade the host cell it disassembles and the genetic material dna or rna of the virus start to interfere with the host cell process. Viruses must first get into the cell before viral replication can occur.

This process culminates in the de novo synthesis of viral proteins and genome. Stages of virus replication. Penetration virus injects its genome into host cell.

During attachment and penetration the virus attaches itself to a host cell and injects its genetic material into it. Viruses are small and lightweight roughly 1 10th the size of a bacterial cell. Attachment penetration uncoating replication assembly and release.

Viral replication is the formation of biological viruses during the infection process in the target host cells. Adsorption virus binds to the host cell. Most dna viruses assemble in the nucleus while most rna viruses develop solely in cytoplasm.

Viral replication involves six steps. Viruses are transferred via virions. Transcription is defined as the process whereby subgenome sized mrnas are produced and coronavirus replication is the process whereby genome sized rna which also functions as mrna is produced thus the generation of subgenomic mrnas involves a process of discontinuous transcription.

Although the specific detail of virus replication vary from one virus to another general replication is same for most virus.
