Hello, I just started to learn perl and just discovered this forum. Anyways what I am trying to do is find genes on a DNA strand and translate them into RNA. (for non biology speakers I am trying to parse a part of the regex, and translate all A's into U's etc...) but when I try to modify $2 parse it tells me that "modification of a read only value at c://blabla.... Any ideas how can I do this? thanks in advance.
