The viral genome is very large and consists of two main parts: the non-synthetic protein region, which includes genes responsible for DNA replication and frontal expression, and these regions are somewhat coherent, so they do not suffer from rapid and frequent genetic mutations. After a large number of years, as was the case in Covid 2019, as for the other region, it is the synthetic protein region, and it includes genetic genes responsible for the structural parts of the virus, such as the envelope, capsid, and spines, and it is fragile, so it suffers from continuous genetic mutations, and for this reason we find the emergence of the so-called modified corona or mutated virus, As these mutations are at the level of the structural sequence of the glycoproteins of the viral spines, which play a major role as specialized sites for binding to cellular receptors. This type of simple mutation is not dangerous, as the body can overcome it through the immunity it has gained through previous infections and vaccination doses, but it may be a danger to certain pathological traits, but healthy, vaccinated people and those who have acquired immunity from previous infections are safe from it.
