I am not sure whether this is the best newsgroup to address this
question.  But certainly, it is read by a lot of people.  The question
that I want to address is whether the organisms have any advantage
having uracil in RNA.  The question was asked by a professor in an
undergraduate microbiology class as a thought question.  The student
came and asked me.  I had never thought about it before and could not
come up with any explanations.  I am sure that there is a good reason
for having uracil in RNA.  Does anyone have any thoughts about it. 
Please reply ASAP.
Thanks in advance.
