Lutionary dynamics of doublestranded (ds) DNA viruses, which may evolve far more slowly than RNA viruses, has not yet been investigated Indeed, the use of heterochronous phylogenetic modeling has resulted in surprisingly high evolutionary rate estimates for JC virus (Shackelton et al 06), variola virus (VARV) (Li et al 07), and the The genomes of viruses possess unique characteristics that are not found in mammalian genomes, such as high CpG content and doublestranded RNA These genomic nucleic acids serve as molecular signatures associated with viral infections Here we show that TLR7 recognizes the singlestranded RNA viruses, vesicular stomatitis virus and influenza virus The recognition of these viruses Animal herpes viruses all share some common properties The structure of these viruses consists of a relatively large doublestranded, linear DNA genome encased within an icosahedral protein cage called the capsid, which is wrapped in a lipid bilayer called the envelope The envelope is joined to the capsid by means of a tegument This complete particle is known as

The genomes of the largest doublestranded DNA viruses such as herpesviruses and poxviruses are quite complex, resembling their host cells Genomes of Polyomavirus are complexed with cellular histone proteins, which form a chromatinlike structure inside the virus particle After infecting the host cell, these genomes behave like miniature satellite chromosomes inside the host cell following the dictates of cellular enzymes and the cell cycle mRNAs of Vaccinia virusThe singlestranded DNA viruses first form a double stranded DNA, utilizing a host DNAdependent DNA polymerase They then undergo a typical replication cycle RNA virus replication with the exception of the orthomyxoviruses and retroviruses, all RNA viruses replicate in the cytoplasm of the host cell The exact process varies with the species of virus The singlestranded RNAMent 11 doublestranded RNA was obtained by using this procedure It provides a general method for cloning doublestranded, RNAs and also nonpolyadenylylated singlestranded RNAs Doublestranded (ds) RNAs that function as genetic elements are widely distributed innature (1) They include the genomes of'eukaryotic members of the order Reoviridae (2, 3), prokaryotic 46
