1. what does it mean to refer to an organism as a

ecombinant\ in the biotechnology field?
an organism that experienced a spontaneous mutation
an organism that grows in a bioreactor
an organism with dna from multiple sources
an organism capable of resistance

1. select all of following that represent advancements due to genetic engineering. (note: please change all question marks to checkmarks for correct answers or empty boxes for incorrect answers.)

medicine and vaccine production
resistant crop production
enhanced nutrition
growth of organic produce
mass production of industrial enzymes

Explanation:

• Question 2: Bioremediation is the use of living organisms (such as bacteria) to clean up pollutants. In the case of the Deepwater Horizon oil spill, certain bacteria were used to break down the oil. Recombinant DNA technology is about combining DNA from different sources, polymerase chain reaction is a method to amplify DNA, and biofuel production is about creating fuels from biological sources - none of these directly relate to oil - spill cleanup in the context of the question.
• Question 3: A recombinant organism in biotechnology has DNA from multiple sources. A spontaneous mutation is a random change in DNA not related to recombination. Growing in a bioreactor is about the environment of growth, not the genetic makeup. Resistance - capability is too broad and not specific to the definition of recombinant.
• Question 4:
• Medicine and vaccine production: Genetic engineering has led to the production of recombinant vaccines (e.g., hepatitis B vaccine) and medicines (e.g., insulin).
• Resistant crop production: Crops can be genetically engineered to be resistant to pests (e.g., Bt - cotton) or herbicides.
• Enhanced nutrition: For example, golden rice which is genetically engineered to have higher vitamin A content.
• Growth of organic produce: Organic produce is typically grown without synthetic pesticides and fertilizers and without genetic engineering. So this is incorrect.
• Mass production of industrial enzymes: Enzymes can be produced in large quantities using genetically engineered microorganisms.

Answer:

1. bioremediation
2. An organism with DNA from multiple sources
3. Medicine and vaccine production, Resistant crop production, Enhanced nutrition, Mass production of industrial enzymes
