Viral Nucleic Acids	2015-08-20		.txt	text/plain	5495	271	54	This scheme in turn places two requirements on the nucleic acid: it must be replicated in the virus-producing cell, to provide the genetic material encased in the progeny virus particles; and it must encode the proteins needed for the production of the progeny particles, including at a minimum the structural proteins from which the particles will be assembled. The DNAs of ssDNA viruses are replicated by a mechanism similar to 'rolling circle' replication, involving synthesis of dsDNA intermediates containing multiple tandem copies of the viral genome. These viruses are unique in that their genomic RNA is translated immediately upon infection; that is, the virus particle is simply a package that introduces an mRNA molecule into the cell. When the particle infects a new host cell, the RNA-dependent DNA polymerase or 'reverse transcriptase' in the virus copies this RNA into dsDNA.	./cache/cord-334082-fyxn0g3v.txt	./txt/cord-334082-fyxn0g3v.txt
