I have to disagree, with respect to my fellow Monks. I enjoy solving other people's problems and, since I'm stalled on my own work, I'm delighted to write your code for you. Besides, your problem looks like fun.

My fellow Monks dislike your post. I don't much like it either -- the tone is way off -- but I'm willing to make allowances. You may sound as if you expect others to be eager to serve you; I don't penalize you for your cultural background.

Still, I will not write your code. Your specification stinks but that's usual and your needs are trivial... right up to the phrase tell whether the sequence is a gene or any regulatory element. This tells me you are one of those damn "biotech" guys who couldn't care less about silicon. You are not one of us who has been oppressed into working for some of them. It's obvious that the problem domain is genetic; but your abrupt slide from parsing a string into a totally unrelated requirement involving an unmentioned database tells me you are not a programmer. And you probably make a fuss every time one of us opens his car door into yours in the parking lot.

So, you're on your own. Maybe you can genetically engineer a recursive monkey to type it up for you.
