Biology Case Study Help

I'd go for cloning because I know most about it but it depends what you find most interesting. It's not that difficult to come up with a few points on each thing but here's a few for cloning:
Good- can be used to produce stem cells
- can be used to make new organs for transplant
- can be used for disease treatment using therapeutic proteins added to cloned animal genomes (look up Dolly)
- production of genetically modified organisms (crops and things like that)
Bad- not a very efficient process
- very expensive
- new procedues available (eg induced pluripotent stem cells from somatic cells)

I don't know if that's at all helpful or the kind of thing youre looking for but it helped with distracting me from what I'm supposed to be doing for a moment.
