Viral transcription takes place in the context of the lifecycle of a given virus: genes necessary early in infection are not necessarily needed late in infection – and vice versa. Viral genomes …

This process – viral transcription – varies depending on the virus family and lifecycle, though a number of general principles are common to nearly every virus. In the case of RNA viruses, …

Replication involves two phases; transcription of the pgRNA from virus DNA in the nucleus followed by reverse transcription in the cytoplasm. In contrast to retroviruses, virus DNA …

A virus must undergo the process of replication to create new, infectious virions that are able to infect other cells of the body or subsequent hosts. After gaining entry into the body, a virus …

Eight steps are generally necessary for a virus to successfully infect a host cell, produce new infectious viral particles, the virions, and release them 6 (Fig. 2): 1) the virus attaches to a host …

Many DNA viruses use this process to cause a transcriptional cascade upon infection. In this process, one of the first viral genes synthesized is a transcription factor that activates a set of …

Jan 22, 2025 · If a virus has a +ssRNA genome, it can be translated directly to make viral proteins. Viral genomic +ssRNA acts like cellular mRNA. However, if a virus contains a …

Jan 11, 2025 · Explore the stages of the viral life cycle, from entry to release, and understand how viruses replicate and spread. Viruses, despite their simplicity, are formidable agents of …

In this review, we describe the key molecular entities involved in the process of infection by SARS-CoV-2, while also detailing how those key entities influence the spread of the disease. …

Genome transcription is a critical stage in the life cycle of a virus, as this is the process by which the viral genetic information is presented to the host cell protein synthesis machinery for the …
