- New Technology
- Using bacteria and yeast
- fermentation
- many useful products made from fermentation
- Antibiotics / Medicines
- Single cell proteins - meat substitute
- Enzymes - food processing and laundry detergent.
- Bio fuels - Ethanol
- involves growing bacteria and fungi
- many useful products made from fermentation
- using bacteria
- reproduce quickly
- no ethical opposition
- bio chemistry is simple
- DNA in form of plasmid
- Can make complex molecules from simple substrates
- fermentation
- Genetic Modification
- genes transferred from one organism to another
- useful for bio chemistry
- genes code for a useful protein
- process:
- required gene is identified and isolated
- gene is then replicated to make copies
- gene is then inverted into the plasmid
- plasmid is then inserted into the organism (bacterium)
- modified bacteria are grown in ideal conditions
- plasmid is then inserted into the organism (bacterium)
- gene is then inverted into the plasmid
- gene is then replicated to make copies
- required gene is identified and isolated
- uses
- making crops resistant to disease
- manufacturing human protein
- making bacteria create medicine
- Nanotechnology
- manipulating and using particles of materials
- can be used for food packaging
- prevent harmful bacteria from growing inside by using silver nano particles as a anti-microbial
- Stem cell technology
- stem cells can develop into any cell
- found in:
- embryos
- umbilical chord
- bone marrow
- can treat leukaemia (blood cancer)
- can be cultured outside the body
- helps repair damage
- Pace makers and heart valves
- human heart has its own pacemaker
- sends impulses to the heart making it contract
- some peoples natural pacemaker doesn't work properly
- doctors insert an artificial pacemaker
- heart valves
- can become fauly
- can be replaced
- 1. Patient is connected to heart-lung machine
- 2. Heart is stopped and opened
- 3. valve is replaced
- 2. Heart is stopped and opened
- 1. Patient is connected to heart-lung machine
- human heart has its own pacemaker
- Genetic Testing
- you can find out about genetic disease
- white blood cells are used
- easily obtained
- 1. Isolation of DNA from white blood cells
- 2. Gene Probe
- 3. Adding a gene probe to a sample of DNA
- 4. Using UV light
- If the gene is present - gel will glow at the point.
- gene probe will bind to the DNA with the gene for the disease
- 4. Using UV light
- chemical is added to the length of DNA
- compliment base pairs of the disease genes.
- 3. Adding a gene probe to a sample of DNA
- 2. Gene Probe
- Using bacteria and yeast
