Transcription of RNA from DNA has alot of amazing steps that amazed me.One of them is that during the proccessing of m-RNA primary transcript,the introns are edited out.My question is if these codons are edited out in this step(they will not be translated) so what is the purpose of having them at all?
Another amazing things :why there is one codon for start and there are three codons for stop?What do you think the resons?And what will happen if there are the same number of codons for both the start and the stop?
or if the opposite happen( 1 codon for stop and 3 for start)????

I'm looking for something top of the line, or close with great resolution that will work with Starry Night Pro. I'm willing to spend a lot so price isn't really an issue.
Any suggestions?
