4. RNA viruses mutate and evolve faster than other viruses. Why
Answers
Answer:
RNA viruses mutate and evolve faster than other viruses because RNA viruses that are present in animal's body show resistance against medications as compared to DNA based viruses which are not resistant to the drugs. Mutation rate of RNA viruses is higher and this mutation helps to keep the population of RNA viruses higher as compared to DNA based viruses. This rate is high because RNA viruses have repair mechanisms system while DNA viruses lack this property.
Answer:
A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell machinery to produce more viruses. Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded.
When the genetic material is single-stranded RNA then it is the RNA virus.
The viruses that have DNA as genetic material are the DNA viruses. They have the mechanism related to the replication of the DNA and the enzymes. The DNA replication enzyme DNA polymerase has a special quality that is the proofreading which prevents the mutations as it eliminates them. whereas in the RNA viruses they don't have this property as they have RNA polymerase and they dot have his tendency and thus the mutation is faster.
