Question 1

what is genetic engineering?

Answer 1

the deliberate modification of the characteristics of an organism by manipulating its genetic material.

Question 2

what are the basic steps in genetic engineering?

Answer 2

These are (1) The isolation of DNA fragments from a donor organism; (2) The insertion of an isolated donor DNA fragment into a vector genome and (3) The growth of a recombinant vector in an appropriate host.

Question 3

what are some of the examples of how different plants/crops have been genetically modified?

Answer 3

Plants have been engineered to tolerate non-biological stressors, such as drought, frost, and high soil salinity. … Several salinity tolerance mechanisms have been identified in salt-tolerant crops.

Question 4

what are some of the potential advantages of genetic modification?

Answer 4

crops have many potential advantages in terms of raising agricultural productivity and reducing the need for (environmentally harmful) pesticides.

Question 5

what are some of the concerns about genetic modification?

Answer 5

Is genetic engineering natural?
Are genetically engineered crops safe to eat?
Can genetic material from genetically engineered crops spread in pollen?
Do patents or genetic traits cause concern?
Are food cultures affected by genetic engineered crops?
