Double-stranded RNA viruses (dsRNA viruses) are a polyphyletic group of viruses that have double-stranded genomes made of ribonucleic acid.The double-stranded genome is used as a template by the viral RNA-dependent RNA polymerase (RdRp) to transcribe a positive-strand RNA functioning as messenger RNA (mRNA) for the host cell's ribosomes, which translate it into viral proteins.
It is a double-stranded DNA virus in the subfamily Tevenvirinae of the family Straboviridae. T4 is capable of undergoing only a lytic life cycle and not the lysogenic life cycle . The species was formerly named T-even bacteriophage , a name which also encompasses, among other strains (or isolates), Enterobacteria phage T2 , Enterobacteria phage ...
Illustrated sample of Duplodnaviria virions. Duplodnaviria contains double-stranded DNA (dsDNA) viruses that encode a major capsid protein (MCP) that has the HK97 fold. . Viruses in the realm also share a number of other characteristics involving the capsid and capsid assembly, including an icosahedral capsid shape and a terminase enzyme that packages viral DNA into the capsid during a
Adenovirus D26 structural model at atomic resolution [1] Adenoviruses (members of the family Adenoviridae) are medium-sized (90–100 nm), nonenveloped (without an outer lipid bilayer) viruses with an icosahedral nucleocapsid containing a double-stranded DNA genome. [2] Their name derives from their initial isolation from human adenoids in 1953 ...
Life cycle of a reovirus. Viruses in the family Reoviridae have genomes consisting of segmented, double-stranded RNA (dsRNA). [4] Because of this, replication occurs exclusively in the cytoplasm, and the virus encodes several proteins which are needed for replication and conversion of the dsRNA genome into positive-sense RNAs.

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell-to-cell movement. Fungi and plants serve as the natural host.
Its genome consists of linear double-stranded DNA, with repeats at either end. The phage is covered by a protective protein coat. The phage is covered by a protective protein coat. The T2 phage can quickly turn an E. coli cell into a T2-producing factory that releases phages when the cell ruptures.
