VIRION
|
Non-enveloped, head-tail structure. The capsid is about 71 nm in diameter. The short tail is non-contractile and measures 15 nm in length by 14 nm in width. Presence of a single tRNA.
GENOME
Linear, dsDNA genome of about 62-64 kb encoding for 77 genes.
GENE EXPRESSION
REPLICATION
CYTOPLASMIC
- Adsorption: the phage attaches to the target cell through its tail fibers.
- Ejection of the viral DNA into host cell cytoplasm.
- Transcription and translation of early genes.
- Replication of genomic DNA. Transcription and translation of late genes.
- Assembly of an empty procapsid and packaging of the genome.
- Viral tail fibers assembly and viral tail assembly.
- Mature virions are released from the cell by lysis.
