I need to be careful about giving answers on multiple choice questions....

For question A, I can explain that Biotechnology mostly takes advantage of the DNA encoding of proteins - most products that are useful to humans and are produced through the biotechnology industry are proteins. Also, the identification of particular genes in living and dead tissues is possible. Multigene traits like newborn human intelligence are the product of a VERY complex interplay of ...
