What results do scientists expect from genetically modified prokaryotes, plants and animals?

The creation of genetically modified plants is most often performed to solve the following specific tasks:
1) In order to increase productivity by increasing:
a) resistance to pathogens;
b) resistance to herbicides;
c) resistance to adverse temperatures, poor soil quality;
d) improving the characteristics of productivity (taste and nutritional qualities, optimal metabolism).
2) For pharmacological purposes:
a) obtaining producers of therapeutic agents;
b) producers of antigens, providing food “passive” immunization.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
