Regarding the post above,
First of all, the OP asked about undergrad. research in general, (whether in regards to the MD or MD/Ph.D., it was never stated). I stated that there were some (NOT VASTLY) that went on to MD/Ph.D without research, in fact I know 5 students that I have taught the past 2 years that were accepted to MD/Ph.D. Even though they wanted to work in labs as the VAST majority of MD/Ph.D applicant do, they could not do so due to working full-time, taking care of their children, or ailing parents. But they showed strong interest in my lab classes by demonstating (e.g. posing question excellent questions, posing other experimental methods to get to the same result, taking part in experimental discussion with myself and professors). In their personal statement they stated why they wanted to do the MD/Ph.D program. I want to state that this does NOT AUTOMATICALLY get you into the MD/Ph.D, but showing intelligent and a VAST interest in research is something. Considering that Medical school want someone in the MD/Ph.D program that will FINISH the program through the END. I knew a couple of students that were extremely intelligent and dropped out of the MD/Ph.D program in favor of the MD in their 3rd year due to personal problems, lack of interest in research, and time. Medical school will not waste their time and accept any applicant who DOES NOT INTEND on finishing the Pd.D in the MD/Ph.D program. If you miscontrue the post then you need to read the post again. I never stated that, "RESEARCH IS NOT IMPORTANT WHEN YOUR APPLYING AS AN MD/Ph.D APPLIANT. Just like everything in life, there are exceptions.
