1. Non reproductive (the book means theraputic) is

  • Genes, cells or whole organisms that carry identical genetic material because they are derived from the same original DNA
  • The use of cloned cells to generate cells, tissues and organs to replace those damaged by disease or accidents
  • 2) as in plants, mass genetic uniformity makes the species unable to adapt to changes in environment 3) animals may not remain healthy in the long term

Other questions in this quiz

2. For the production of drugs eg penicillin the fungus

  • Ethical objections, and some people think there is a lack of understanding on how these clones will behave over time
  • Penicillum are grown in culture and produces the antibiotic as a by-product of its metabolism
  • 2) as in plants, mass genetic uniformity makes the species unable to adapt to changes in environment 3) animals may not remain healthy in the long term
  • 1) enzymes not present with products so downstream processing cost low 2) enzymes are immediately available for reuse 3) immobilised enzymes are more stable as the matrix protects them

3. There are many possibilities of theraputic cloning, eg 1) regenerating heart muscle following a heart attack

  • Genes, cells or whole organisms that carry identical genetic material because they are derived from the same original DNA
  • 2) repair of nervous tissue from diseases such as multiple sclerosis 3) repair of the spinal chord
  • 2) often produce proteins or chemicals that are released into the surrounding medium and can be harvested 3) can be genetically engineered to produce specific chemicals 4) not dependant on climate 5) purer products than those from chemical synthesis

4. Batch culture is where

  • 1) enzymes not present with products so downstream processing cost low 2) enzymes are immediately available for reuse 3) immobilised enzymes are more stable as the matrix protects them
  • A fixed quantity of nutrient is added and products are removed at the end of the period, useful for secondary metabolite production
  • 1) immobilisation requires additional time, equipment and materials 2) immobilised enzymes may be less active as they are held separate 3) any contamination is costly as the whole system would need to be stopped

5. Biotechnology is

  • 1) enzymes not present with products so downstream processing cost low 2) enzymes are immediately available for reuse 3) immobilised enzymes are more stable as the matrix protects them
  • Technology based on biology and involves the exploitation of living organisms or biological processes, to improve agriculture, animal husbandry, food science, medicine and industry
  • Ethical objections, and some people think there is a lack of understanding on how these clones will behave over time
  • 2) often produce proteins or chemicals that are released into the surrounding medium and can be harvested 3) can be genetically engineered to produce specific chemicals 4) not dependant on climate 5) purer products than those from chemical synthesis
