Dna Virus Examples

Some common examples of dna viruses are parvovirus papillomavirus and herpesvirus. Prominent disease causing dna viruses include herpesviruses papillomaviruses and poxviruses.

There are a total of eight herpesviruses that infect humans and establish latent infection.

Dna virus examples. In other words viruses. Small dna viruses do not encode an entire replication system encode proteins that orchestrate the host papillomaviridae polyomaviridae parvoviridae large dna viruses encode most of their own replication systems herpesviridae adenoviridae poxviridae 10. Dna viruses essentially turn host cells into virus factories.

Dna viruses belonging to papovavirus adenovirus hepadnavirus and herpesvirus families have been associated with tumours in man and animals o shea 2005. Dna viruses comprise important pathogens such as herpesviruses smallpox viruses adenoviruses and papillomaviruses among many others. The structure of herpes viruses consists of a relatively large double stranded linear dna genome encased within an icosahedral protein cage called the capsid which is wrapped in a lipid bilayer called the envelope.

Adenovirus herpesvirus and poxvirus are all examples of large dna viruses that infect humans. Dna viral infections such as colds and flus are usually highly communicable because they spread by broadcasting new viral packets into the environment. Adenoviruses of which there are many types cause gastroenteritis and respiratory disease in humans.

These host cells fill with newly manufactured viral packets and then release them usually by bursting to infect other cells. Herpesviruses are a very diverse family of viruses. Herpesviridae is a large family of dna viruses that cause diseases in animals including humans.

Dna viruses can affect both humans and animals and can range from causing benign symptoms to posing a very serious health risk. They appear to have multiple origins as viruses in monodnaviria appear to have emerged from archaeal and bacterial plasmids on multiple occasions though the origins of duplodnaviria and varidnaviria are less clear. A biological virus whether it is a true virus an endogenous retrovirus or a transposon can literally lay dormant in a word document as a string of as ts cs and gs.
