What Is A Mutant Strain Of A Virus

Well first viruses have a mutation rate thats much much higher than humans or other animals and they replicate at a rate thats really really fast. This means the virus is making copies at a faster rate further newer mutants are emerging faster.

Reportedly 17 mutations occurred in the.

What is a mutant strain of a virus. Scientifically speaking a mutant is the result of a mutation a change in the genetic material DNA or RNA and produces something new. A variant usually doesnt affect how the virus works. The team of experts revealed their findings in a preprint research paper which reports the coronavirus variant carries 34 mutations.

A mutation is a change in a viruss genome which is the set of genetic instructions that houses all the information the virus needs to function. The double mutant virus is proving to be more dangerous there is a constant change in its genetic structure. Mutating viruses are more contagious but the virulence of such virus continues decreasing with each mutation.

It is predominantly circulating in West Bengal. Although most genetic changes are innocuous some can make the mutant more adept at. Subscribe to our email newsletter Subscribe.

The mutant is said to have a transmissibility rate of 70 which is high. Viruses mutate all the time including the SARS-CoV-2 coronavirus thats caused the Covid-19 pandemic. Experts say this variant is more infectious and is spreading rapidly.

Mutations in viruses are common but most of them are insignificant and do not cause any change in its ability to transmit or cause serious infection. The new mutant was discovered early September 2020 but between then and the middle of December 2020 it has spread very quickly much faster than previous strains of Covid-19. So in other words one virus-infected cell makes 100000 copies of itself and all those copies can go out and start replicating.

But sometimes they make it act in different ways. A mutant is the result of a mutation which is a change in the genetic material DNA - RNA and produces something new. Scientists have detected what is believed to be the worlds most mutated COVID strain as fears grow that new super variants may prolong the pandemic.

Geographic separation tends to result in genetically distinct variants he says. Viruses are always changing and that can cause a new variant or strain of a virus to form. Ray says it is the nature of RNA viruses such as the coronavirus to evolve and change gradually.

Variants of viruses occur when there is a change or mutation to the viruss genes. Read on to know more about it. Mutation refers to the actual change in sequence.

And so mutation is not something to be worried about because it results in a milder. Mutations have been observed in other strains of the Sars-CoV-2 coronavirus that causes Covid-19 but they usually occur as one mutation. The triple mutant variant or the Bengal strain is a new variant of the Covid-19 virus that has been detected in India.

Mutation is the process by which a strain can take on new variants.
