Non enveloped double stranded dna virus
Non enveloped double stranded dna virus-Virus Virus Annotated classification DNA viruses Family Poxviridae Large viruses of complex structure with dimensions of 400 × 250 nm, the genome of which is linear doublestranded DNA Virions contain at least 40 proteins and lipids, as well as internal structures called lateral bodies The 2 subfamilies are called Chordopoxvirinae, which infect vertebrates and are closely relatedJun 02, 21 · On the other hand, variola virus is an enveloped virus that belongs to the genus Orthopoxvirus and causes smallpox infection Thus, this is the key difference between vaccinia and variola virus Moreover, the doublestranded DNA of the vaccinia virus is 190 kbp in size In contrast, the doublestranded DNA of variola virus is 186 kbp in size

(a) Rabies virus has a singlestranded RNA (ssRNA) core and an enveloped helical capsid, whereas (b) variola virus, the causative agent of smallpox, has a doublestranded DNA (dsDNA) core and a complex capsidDec 01, 19 · The virus has been isolated from T ni and transmitted per os and by injection to T ni and several other species of the family Noctuidae The virions produced by this virus are large (ca 130 × 400 nm), enveloped, and allantoid in shape with complex symmetry and contain apparently linear, doublestranded DNA of Mr of ≈ 100 × 10 8Classification of Viruses Viruses can store their genetic information in six different types of nucleic acid which are named based on how that nucleic acid eventually becomes transcribed to the viral mRNA (see Fig 1) capable of binding to host cell ribosomes and being translated into viral proteins In the diagrams below, () and () represent complementary strands of nucleic acid
B19, database# 1S58 Parvovirus B19 virus is part of the parvovirus family and causes a childhood rash called fifth disease or erythema infectiosum that is commonly called slapped cheek syndrome B19 is a nonenveloped virus whose capsid protects a single stranded linear DNA genomeJun 25, 17 · Most doublestranded DNA viruses replicate within the host cell nucleus, including polyomaviruses, adenoviruses, and herpesviruses—poxviruses, however, replicate in the cytoplasm Adenoviruses and herpes viruses encode their own replication factorsThe genomes of viruses can consist of 1) singlestranded or doublestranded DNA, 2) singlestranded positivestrand RNA (or sense RNA), 3) singlestranded negativestrand RNA (or antisense RNA), or 4) double stranded RNA that is covered by a protein coat called a nucleocapsid
Positive single stranded RNA viruses;(a) Rabies virus has a singlestranded RNA (ssRNA) core and an enveloped helical capsid, whereas (b) variola virus, the causative agent of smallpox, has a doublestranded DNA (dsDNA) core and a complex capsidEnveloped and contains partially doublestranded circular DNA that is enveloped Viruses carry a DNA polymerase with reverse transcriptase activity to synthesize an RNA intermediate that is then used to make genomic DNA This family of viruses replicates in the nucleus, differentiating it from the Poxvirus family

Genome serves as a giant mRNA;A) enveloped viruses – envelope present (mostly animal viruses) b) naked viruses – no envelope present Nucleic acid core a) DNA viruses · Singlestranded DNA parvovirus only · Doublestranded DNA all the rest of the DNAcontaining viruses b) RNA virusesWe have found that mycoplasma virus L172 is an enveloped globular virion containing circular, singlestranded DNA of 140 kilobases L172 has been reported by other workers to have a doublestranded DNA genome of 13 to 17 kilobase pairs and has been classified as a plasmavirus, a group for which mycoplasma virus L2 is the type member
