does corona virus is changing its DNA.. if yes than till now how many times DNA of corona virus has been changes
Answers
Answer:
The transmission is necessary because of two reasons. First, the process of replication takes a toll on the host. When that toll is high enough, the virus ends up killing the infected individual. The death of the host is an unfortunate consequence of the viral infection, and it is detrimental to both the host and the virus itself. So the virus must establish a new infection before it destroys its present host. This is hardwired in the virus’s DNA (or RNA).
A virus that can’t transmit before it kills can’t continue to exist forever. Proof of this statement lies in the fact that viruses that can kill quickly, in a matter of weeks – such as Ebola and influenza – are all transmitted very quickly. They have to in order to avoid extinction. The converse is also true: HIV takes years to kill, and it also has more sophisticated modes of transmission that are unlikely to infect a large number of people in a short span of time.
