As I recall
Genetic engineering as you have stated requires the 'physical' manipulation of Deoxyribosenucleic acid chains in specific areas sometimes known as gene sequences. I'm sure it's much more complicated but I had to study ecology for A level Biology rather than cellular biology, genetics and DNA were a self study 'cause I watched the Horizon documentary on the discovery of the shape of DNA, (brilliant by the way, not 100% bang on but really good).
selective breeding is something very similar, but isn't done at the molecular level, but at the 'physical' level by breeding specimens that display physically or mentally the characteristics you want in the offspring. Sort of like Darwins natural selection of the best mutation to survive, but by deliberate manipulation. An example of this would be breeding the seeds out of the common banana, or the terrier.
The experiments on Drosophila melanogaster originally were mostly based around genetics, for instance to discover that genes were related to proteins and to study the rules of genetic inheritance but research has been expanded and recently it's genome has been totally mapped, see guys we do have something in common with a fruit fly!!
For those not familiar with the fruit fly they have an extremely short life/breeding cycle, (2 weeks), but are complicated enough to display obvious mutations. They are cheap to buy and look after and are extremely succeptible to UV radiation to cause mutations. Make a mutation, breed it and look for the genetic patterns to see how inheritance works. A fast version of evolution by mutation.
anything else go look on the internet, that's pretty much all I remember.
Having a beer and trying to remember. I always find beer helps my memory....pity I couldn't have taken my A levels bladderedOriginally posted by manike
I guess selective breeding isn't covered by the text book definition of GE.
"genetic engineering
n.
Scientific alteration of the structure of genetic material in a living organism. It involves the production and use of recombinant DNA"
where's Cube when you need him?
