In school I have to do a report on genetic engineering in antibiotics and what is it and how its used and so on. I've looked at various articles online and can't seem to get what it really is and how its done. Could someone please tell me what genetic engineering in antibiotics is?

If you are having problems break it down into things you DO understand.
So start with Genetic Engineering: Genetic engineering - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Genetic_Engineering)
Then go for Antibiotics: Antibiotic - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Antibiotics)

Then put it all together.
