CV with academic transcript I am going to apply for a visiting research program in Physics. The institute asks for a Curriculum Vitae (a single pdf file) which will provide all my  academic background and professional background info, copies of my academic transcripts, and a Statement of Purpose describing my background and explaining why I feel that the program is right one for me.

I have an "ordinary" CV. Now I am a bit confused about how to add all those things into one such CV. Please suggest me how to go about it. If there are some sample documents,please let me know.
This sounds like a case of the ambivalent comma to me.  In the quote that you provide:


  "Please attach here (in PDF format only) your Curriculum Vitae, which will provide all of your Academic Background and Professional Background information, copies of your academic transcripts, and a Statement of Purpose describing your background and explaining why you feel that this is the right program for you".


it is ambiguous whether it should be interpreted as "Curriculum Vitae (which has your background) and copies of your academic transcripts and a Statement of purpose" or as "your CV should have: academic and professional information and copies of your academic transcripts and a Statement of purpose"

The typical practice would be for an institution to be requesting the second, so I would recommend interpreting it in that manner.  If they allow you to upload only one PDF, just bundle the documents together into one PDF.
