Chapter 38, Problem 38.3CR
Summary Introduction
To review: How genetic engineering has improved the quality of food.
Introduction: Genetic engineering allows the direct transfer of gene of interest, between the closely or distantly related organisms. This technique involves the use of laboratory tool to cut, alter and insert the pieces of DNA that contain the gene of interest. Genetically modified crops can contain a gene that has been artificially inserted into the plant genome instead of pollination. The resulting crop is said to be “genetically modified” from their wild (original) state.

Describe some of the main techniques used in biotechnology to genetically modify food.
Genetic engineering is a process causes the production of GMOs ( Genetically Modified Organisms) due to the ideas of biologists. The presence of the products contributes the division of the society in relation to GMOs effects.
TASK:
You serve as a genetic engineer, if you are given a chance what GMO would you like to produce?
What to do:
Give a name of your GMO
Illustrate and/or describe your GMO
List all the possible pros and cons
Briefly discuss the following concerns of Biotechnology;(i) Monoclonal antibodies technology versus gene technology for cancer treatment.(ii) Traditional plant breeding versus Gene technology: Which is the more efficient way for pesticide resistant crop production?(iii) Chemical technology versus Enzyme technology in industrial application.(iv) Are genetically modified organisms (GMOs) a threat to the environment?

- List five genetically modified organisms (either plant or animal) in agriculture and identify the traits modified or engineered for each of them.arrow_forwardMuch of the controversy over genetically engineered foods has centered on whether special labeling should be required on all products made from genetically modified crops. Some people have advocated labeling that identifies the product as having been made from genetically modified plants. Others have argued that food labeling should be required to identify only the ingredients, not the process by which they were produced.
