...DNA (the blueprint) to proteins (the cells’ workhorses). We have shown that some small RNAs are specifically expressed by dormant cancer cells. Since these RNAs can be measured in urine and blood samples, we and others are trying to develop new diagnostic tools to detect these molecules. If we are successful, we will be able to create blood or urine-based diagnostic...

...DNA) the development and proper use in the relevant instances of specialist tools and standard operating procedures based on the above. Arguably there is also a third instance: when a forensic technician examines a specific item of evidence and reports the findings. This must be ‘scientific’ to the extent that it is repeatable by others. In criminal law procedure, the...

...DNA, and they are passed on from our parents. Genes determine certain simple traits, such as eye or hair colour, but they can do so much more. They can influence our personality, behaviour and even what food we like! Taste is a very complex trait, and it can be influenced by many things. From which foods your mother ate while you were in her womb to any negative...

...DNA, represent diversity below the species level. [A lion on the Djuma Game Reserve, South Africa] South African born and bred: A lion in the Djuma Game Reserve Translocations and reintroductions may be able to bring back previously lost species and functions. This makes them a promising tool for conservation. On the negative side if genetics are not considered when...

...DNA and causing cancer, alpha particles act more like a normal poison, but damaging many different biological systems rather than targeting one type of molecule. The effects of polonium poisoning are effectively those of acute radiation poisoning. These occur within one day of exposure to a large dose of ionising radiation. The effects are all based on damage occurring to...
