Answer #1

I will provide you answer for first question rest will be answered by other experts.

1.Protein-protein bond is a physical contact of high speacificity between two or more protein molecules by biochemical events steered by electrostatic forces including the hydrophobic effect.

Protein- protein interaction occurs through combination of hydrophobic bonding,Vander walls forces and salt bridges at specific binding.

    1.In early March, it was reported that two main strains of SARS-CoV-2 had been identified, termed S and L, with the S type being the less virulent ancestral form representing about 30% of prevalence and the more virulent L type having descended from the S type and representing about 70% of prevalence. However, the prevalence of the more virulent L type seems to have decreased after early January, and it is thought that this resulted from human intervention against this...
