Answer:

Viral proteins can modify the most superficial portion in such a way that it is complementary to the receptor of the human cell.

Generally this happens due to a genetic recombination between an avian virus and a human virus within the respiratory epithelium of the pig: this process underlies the emergence of new, more virulent strains of the influenza virus and underlies the emergence of influenza pandemics

Do you think that genetic testing is ethical right or wrong?
nydimaria [60]

Answer:

Genetic testings is very ethical in a sense that it helps determine the DNA of a child.

Explanation:

Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder. This means that a family can find out whether their child has autism before it is even born, or discover a potential mutation it might have. It is a cautious procedure but inhabits the well being of a child.
