Tiny Animals

Post by Khaiy » Wed Feb 28, 2007 4:35 am

I saw a picture in my biology textbook of a transgenic tobacco plant which had genes from a firefly spliced into it, and so the whole plant bioluminesced.

This got me thinking. Would it be possible (in theory at least) to identify genes for growth (since growth is largely determined by genes) in a small animal, say an inch or so long, and then splice it into a larger animal, while at the same time removing the larger animal's growth-related genes? And then have as a result an animal (like a tiger) that is only an inch long?

Obviously there would be some technical issues in doing this, namely identifying all genes related to growth, and being able to remove them without causing serious problems in other areas of development. But could it potentially work?

No, as you might have guessed, the genes code for different proteins/organic molecules...there's no general "growth" factor that you can simply multiply by.
