Virus with DNA (Dna virus)

DNA Virus

DNA viruses is in the monix and higher points. Let's begin with the basic viral structure as shown in figure above. In this picture basic viral structure consists of viral genome which is DNA or RNA in the center which is surrounded by nucleo capsid and the third important viral structure is the envelope based on these three structures.

viruses can be classified into various groups based on genome files can be DNA virus or RNA virus based on nucleic acid. viruses can be helical or icosahedral and best an envelope viruses can be enveloped or non-enveloped.

Now let's move to the DNA virus family. DNA virus family comprises of parvovirus, papilloma virus, polyomavirus, adenovirus, herpes virus, Padma Paris and pox virus. To remember these viruses who can use the mnemonic pardon papa is he has box. DNA where pardon is for parvo virus, Papa is for papillomavirus and polyomavirus. Hayes is for adenovirus he is for herpesvirus has his fur a partner virus boxes fur pox virus and DNA is for DNA viruses.

Now let's learn some general rules for DNA viruses

 Most of the DNA viruses are double-stranded second release whereas most of the DNA viruses have icosahedral, symmetry hard release, most of the DNA viruses replicate in the nucleus and the fourth rule is most of the DNA viruses have linear genome each of the rule has exception part of virus is the only single-stranded DNA virus. Box virus is the only virus with complex capsid pox virus is the only DNA virus which does not replicating nucleus and papilloma virus volume of virus and her partner virus have circular genome unlike other DNA viruses to remember DNA viruses with circular genome.

We can use the mnemonic pop art poverty is snack taken in the Indian subcontinent which is circular and BA from Papua is for papilloma boys for Paloma and SD is for her partner virus now let's move to the naked DNA viruses. To remember naked DNA viruses will use the same mnemonic which we use for the DNA virus family that is parent Papa yet she has box tyranny but we'll be using only the first three words pardon is for parvo virus Papa is for papilloma virus and all the uma. virus and ads is for adenovirus rest of the DNA viruses are enveloped viruses.

Classification of DNA virus

Today we will be doing the classification of medically important Viruses. There are two groups depending on the nucleic acids that they contain DNA and the RNA viruses.

In this Article we will only be speaking about the DNA viruses. There are six DNA viruses in total and we will write them according to you the family. So if you want to write the family you have to write very day at the end of it and then for the genus and the species lips both virus.

first one is family herpes

 second one is pox every day the

third one would be I'd know there a day

followed by a patent every day then

epilim every day and parvo very day. So

you can think of it as henry peels all his potatoes properly you've got herpes pox I don't know a partner papilloma and parva here are the exceptions to make it easier for you. So all of them are a certain kind of way except the a couple of them that are different so we're gonna have some signs to differentiate them so the asterik would be complex the plus sign would be single strand. Now if their DNA they should be single there should be double stranded but some of them are single stranded a dot would represent whether they are enveloped or not and in green were right there shape of their DNA whether they're circular or linear or segmented.

All of them are linear but a partner at papilloma are circular. None of them are enveloped except the first one so Happy's very day gets at all and now we move on to complex now. All of them are icosahedral except pox verde which is complex so we've got icosahedral complex spherical wart filamentous Palo Verde and her patent every day have a single-stranded DNA.

DNA virus diseases

Now we will move on to the medically important one starting with a ferrets family herp is very day it's got six viruses under it they're called human herpes virus viruses 1 to 6. So the first one is the first and second one actually are called herpes simplex virus is the coat bone and tooth. They cause herpes and encephalitis the second one would be varicella-zoster virus

and they cause varicella and sauce episode stir they are known as hume human herpes virus number three third one would be epstein-barr virus

 which causes infectious mononucleosis which affects our immunity and it is known as the herpes virus number four

Next would be cytomegalovirus C and B which causes congenital disease.

Image : cytomegalovirus infection

 It's very common and infectious mononucleosis in immunocompromised patients and it would be Epis virus number five and the last one Happy's virus number six is known by the same name and it causes roseola.

Moving on to the next family proxy a day has three viruses we've got smallpox virus which causes smallpox then we've got vaccine which causes cow pox and the third one would be a milder smallpox disease caused by monkey pox maybe want to add an everyday the virus genus has the same name. so it would be a Tanner virus and it causes respiratory diseases conjunctivitis and gastroenteritis then her patent every day is to do with the hepatitis B virus which obviously causes the liver disease.

 Hepatitis and pabulum every day is the human papilloma virus HPV and it's to do with warts cervical dysplasia cervical carcinoma parvo very day the last one the name of the virus is parvo virus and it causes erythema infect Co so that would be it for the DNA viruses.
