The single-stranded dna phages
WebEntry: The phage injects its double-stranded DNA genome into the cytoplasm of the bacterium. DNA copying and protein synthesis: Phage DNA is copied, and phage genes are expressed to make proteins, such as capsid proteins. Assembly of new phage: Capsids assemble from the capsid proteins and are stuffed with DNA to make lots of new phage … WebDec 2, 2010 · Here, we describe two complete ssDNA phage genomes that were reconstructed from a viral metagenome from 80 m depth at the Bermuda Atlantic Time-series Study (BATS) site in the northwestern Sargasso...
