WebSmall circular single-stranded DNA viruses of the Microviridae family are both prevalent and diverse in all ecosystems. They usually harbor a genome between 4.3 and 6.3 kb, with a microvirus recently isolated from a marine Alphaproteobacteria being the smallest known genome of a DNA phage (4.248 kb). WebThus, although the RNA genome is single-stranded, it adopts specific secondary structures within capsids with many double-stranded regions; these regions are thought to play essential roles ... structurally well-characterized double-stranded DNA bacterio-phages, where the DNA is visible only as closely packed con-centric spheres within the ...

"WebAfter the single-stranded viral DNA enters the cytoplasm, it serves as a template for the synthesis of a complementary DNA strand. This synthesis is initiated in the intergenic region of the DNA sequence by host RNA polymerase, which synthesizes a short RNA primer on the infecting DNA as template.
