I agree somewhat with the post above, although I'm still just a lowly premed.
He/she is right however, without good grades and other items listed in the previous post research will probably not help your med school application. However if you like research and plan to work very hard at it then its a great experience.
Alot depends on your preceptor and what they expect from you. I've heard stories about preceptors that just have you do readings and basic background stuff without actually letting you get involved in real experimentation.
As far as getting admitted to these programs, there are several who favor those with no research experience, but the big programs (i.e. NIH, NSF, etc) I think tend to favor previous research experience. The way most of the national programs work is that they circulate your application to the individual researchers who then select people from the stack. So alot depends on the individual researchers who look at your app. Some want people who are completely new to research, while others want a die-hard research god.
So no matter what, if you are really interested in research and spread your apps around, you should be able to land something whether or not you have any previous research experience.
Remember, a clinical doctor can touch thousands of lives in his/her lifetime, but a medical researcher has the potential to touch millions.
