An initial analysis of the new strain was published and identified 17 potentially important changes, and there were changes in the "spike" protein, which is the key the virus uses to open the entrance to the body's cells.
One mutation called N501Y alters the most important part of the spike known as a "receptor-binding domain". This is where the spike first comes into contact with the surface of the body's cells, and is likely to give it any Changes that facilitate the entry of the virus into the interior of an additional capacity for infection.
Also, a mutation was recorded that led to the deletion of a small part of the spike, and the name of this change is “H69 / V70 deletion”. Studies indicate that this change makes the antibodies from the blood of survivors less effective in attacking the virus.
How did the mutation happen?
The variable is extremely mutated in an unusual way, and the most likely explanation is that the mutation appeared in a patient with a weakened immune system unable to overcome the virus, and instead his body became fertile ground for the virus to mutate, according to a report by James Gallagher in the " BBC " (BBC).
