Most DNA viral polymerases have an exonuclease domain which can check DNA for errors and then repair these errors (HSV). RNA viruses such as polio do not have this domain in their viral polymerase, and therefore do not proof-check their genome as other DNA viruses do. This leads to more mutations....

Viruses multiply the same way as other organisms?
I don't know about the same as other organisms,but definitely faster!MUCH faster!
What are some things bacteria and viruses have in common?
Bacteria and viruses can both infect many species unrelated to each other. Rabies as a viral example, and staphylococcus as a bacterial example. Both can cause disease. They are able to mutate within a short period of time (few generations).Neither bacteria or viral organisms have a nucleus.
What do viruses have in common with bacteria?
Viruses van cause diesease and so can bacteria they are both microscopic they can evolve they have DNA they can reporduce (even though viruses can only reporduce in a cell) they are passed through the air They have both caused plagues
Why are viruses so hard to kill?
bcoz some viruses are able to survive even in extreme hard conditions like high temperature. For those medicines r used which breaks the bases of their DNA. REMEMBER..... viruses r prokaryotic and they r from the very beginning of life on earth. they infect the hosts and more viruses r created and .......u know what For more visit.. http://en.wikipedia.org/wiki/Virus#Bibliography. they also have a protein coating which is hard to break in to.
Why is vaccine developed for influenza but not for rhinovirus?
Because the rhinovirus (which is one virus that causes the common cold) mutates and changes its structure extremely frequently as do the other viruses that cause the common cold, such as Coronaviruses, and any of the others of hundreds of viruses that cause colds. While influenza strains also mutate, it is not as quickly as cold viruses that almost constantly are mutating, resulting in several dozen active viruses in any one locality. In addition, influenza has proven reasonably easy to grow in labs for study and for vaccine production, while cultivating rhinoviruses has proven very difficult.
State any one reason to explain why RNA viruses mutate and evolve faster than other viruses?
It's because the enzyme RNA dependent RNA polymerase that synthesizes RNA does not have the activity of proof reading while DNA polymerase has this activity. Because of this absence of proof reading, wrong bases are inserted without correction and hence mutation is faster.
How viruses change every year?
you see viruses have the ability to mutate to better it's survival in the hosts body since your immune sysem records data on them before they mutate we can be effected the next year because of it's changes. In other words it can mutate it self over and over to keep it self going. example the common cold you can catch a different cold from the same virus because it mutated in the hosts body.

How does swine flu get destroyed without antibiotics?
You cannot destroy a virus with antibiotics, because antibiotics kill bacteria not viruses. Tamiflu and other meds similar attack the virus, but it is not always successful, as viruses are quick to mutate and become immune to antivirals out there.
When do viruses evolve?
Viruses evolve primarily when they replicate and undergo mutations during their replication process. This can occur in response to environmental pressures, such as host immune responses or antiviral treatments. Additionally, viruses can exchange genetic material with other viruses through reassortment or recombination, leading to significant evolutionary changes. Overall, the rapid replication rates and high mutation frequencies of viruses facilitate their evolutionary adaptability.
Do flu viruses have a high mutation rate?
Yes, viruses do mutate very easily. This is one reason the cure for the common cold is so elusive, before a vaccine can be created for the strain of rhinovirus or other virus that is causing the currently circulating common cold, the viruses will have often mutated to a new form making a vaccine ineffective.
How do viruses adapt?
Viruses can adapt through mutations in their genetic material, allowing them to evolve and develop new characteristics. This can occur during replication inside host cells or through recombination with other viruses. Adaptation enables viruses to overcome immune responses, change host range, or develop resistance to antiviral treatments.
What does it mean when organisms evolve?
When organisms evolve, it means that they have undergone genetic changes over time that result in new characteristics or adaptations that allow them to better survive and reproduce in their environment. Evolution is driven by natural selection, mutations, genetic drift, and other factors that lead to changes in the genetic makeup of a population.
What do you use bio matter for in Mutate the Lab Rat 2?
To craft other foods.
Why are viruses such successful agents?
Viruses are successful because a) They use the DNA of their infected host to replicate themselves. b) They mutate (change) their basic characteristics to avoid being irradicated by either the host's immune system or antiviral agents. c) Many viruses are quite hardy and able to live in a dormant state until a suitable host is found, at which time they replicate quickly, are discharged by the host's cells, and are then available to infect other suitable hosts.
How do use the radiation in mutate the hamster?
I've never heard of Mutate The Hamster, but I'm guessing you mean Mutate The Labrat, or Mutate The Labrat is similar to Mutate The Hamster. But here's what I know about the radiation. You have to use the radiation a bit at a time or else the rat will die. Plus, you have to constantly feed it until the radiation wares off, and make sure that there is no other chemicals in its system (like mutagen X) or else the toxication will be too high, and it will die. I hope that helped.
What type of program is a backdoor?
