relationship between pCRESS2 and GasCSV-like viruses, viruses of the latter group might infect bacteria rather than eukaryotes. Alternatively, the transition from a plasmid to a CRESS-DNA virus ancestor could have occurred once and was followed by replacement of therepgenes with counterparts from ot...
Virus-derived small RNAs were accumulated from virus-infected wild-type strains with strand bias towards the negative sense. The findings of these studies indicate thatS. sclerotiorumhas robust RNA silencing mechanisms that process both DNA and RNA mycoviruses and that, when both dicers are silenced,...
Single-stranded DNA n., Definition: DNA of only one strand. Credit: Microvirus diagram (Fdardel, CC BY-SA 3.0) Table of Contents What is single-stranded DNA? DNA is the material that living organisms possess that carries their genetic make-up. DNA and RNA are sometimes confused with...
virus-associated human diseases. Our results support that CRESS-DNA viruses can infect non-eukaryotes, which would mean that smacoviruses are the viruses with the smallest genomes to infect prokaryotes known to date. A probable target strand bias suggests that, in addition to double-stranded DNA,...

ICP8, the herpes simplex virus type-1 single-strand DNA-binding protein, was recently shown to promote strand exchange in conjunction with the viral replicative helicase (Nimonkar, A. V., and Boehmer, P. E. (2002) J. Biol. Chem. 277, 15182-15189). Here we show that ICP8 also cataly...

Thesingle-stranded DNAof the lagging strand created by the action of the helicase is covered by tightly binding single-stranded DNA-binding proteins. InE. coli, this protein is a tetramer known as single-stranded-binding (SSB) protein, which the ssDNA winds itself around, while in T4 and T...
