user22601: I accidentally worded the following question wrongly:
Why are the granules of pancreatic alpha cells larger than those of beta cells?
What shall I do now? Should I ask a new question or edit the existing question? 
Will the OP of the current answer appreciate it if I change the question at this stage when it renders his answer basically meaningless?
Since the current question is incorrect, I would prefer to edit it. 
Edit : Answerer could have have asked me in comments to recheck my question, rather than explaining in full length I exchanged the size of two.
I also believe this would waste my reputation(that is already too low) on bounty , for such non needed answer. 

user9943: What should the question have been? Generally spoken, when the edit is small and renders existing answers not worthless, the question should be edited.
However, assuming the intended question is very different than the existing original question and since the answer has received 4 upvotes and seems to be qualitatively sound, I would recommend asking a new question, perhaps linking the existing original question.
However, it all depends on how different the intended question is from the existing original question.
