- engineering case studies-golden rice
- lack of vitamine a can cause blindness
- childeren and pregnant women are more at risk
- vit A affects homeobox genes-body plan
- childeren and pregnant women are more at risk
- Vit A only comes from animal sources
- beta caroteine found in plants can be converted to Vit A in human gut
- vit A is fat soluable so lipids must be consumed with it
- needed for cell growth and development
- essential for growth of bones
- needed for maintenance and differentiation of epithelial cells
- the grain of the rice plant contains an inactive gene for production of beta carotein
- in order to 'switch on' gene for beta carotein production in endosperm(grain) of rice plant two genes had to be inserted into the genome
- Advantages
- reduces cases of blindness in developing countries
- provides source of vit A
- Disadvantages
- reduces biodiversity
- long term effects unknown
- could breed with wild rice and contaminate wild rice populations
- lack of vitamine a can cause blindness
