2. Theraputic cloning is not currently allowed to be used as people have
- Ethical objections, and some people think there is a lack of understanding on how these clones will behave over time
- 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. Primary metabolites are
- A growth of microorganisms, this may be a single species (pure culture) or a mixed species (mixed culture), microorganisms can be cultured in a liquid such as nutrient broth or a solid surface such as nutrient agar gel
- 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
- Substances produced by an organism that are part of its normal growth, they include amino acids, proteins, enzymes, nucleic acids, ethanol and lactate
- 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
4. In 2008 skin cells could be reprogrammed to become pluripotent, which would have less
- Ethical objections and if this method can be proven to be safely developed the technique could replace the nuclear transfer method
- 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
- Ethical objections, and some people think there is a lack of understanding on how these clones will behave over time
5. The advantages of immobilising enzymes are
- 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 growth of microorganisms, this may be a single species (pure culture) or a mixed species (mixed culture), microorganisms can be cultured in a liquid such as nutrient broth or a solid surface such as nutrient agar gel
