I have simple question that bothers me for a while so I would like to sort it out.
If I have 2 different RNAs with very different length than I think 10ug of one RNA size sample is not the same as 10ug of the RNA of different size.
If I want to comapre them in experiments I think I would need to calculate their molarity in order to have same number of molecules in a sample.
Am I right?
If so, (or if not), my next question would be in what condition would I need their weight concentration actually?
