Dear netters,
I am a first year undergraduate,so don't get angry if this question is 
too stupid.I want someone to explain to me Convincingly how the formation 
of a mRNA stem-loop structure causes the termination of 
transcription.Given the length of the sequence itself,isn't it possible 
for several such structures to form along the way? How is it thus ensured 
that the termination occurs at the right site?Does the stem - loop 
structure allosterically inhibit the nearby RNA Polymerase or are other 
factors involved? What role does the size and complexity of the stem - 
loop structure play in the termination? Please help!
