March 25, 2015. The rise of the Islamic State (IS) in Iraq and Syria has turned up the heat on Iran and its allies. The Islamic State, a radical Sunni group, is a danger to Shia Iran and its allies, whom it hates and refers to derogatorily as rafida, or ârejectersâ of Islam, a status that makes them fit to be slaughtered.
How might an error in the DNA of an organism affect protein function? Deoxyribonucleic acid (DNA) transcription occurs at a rate of  around 1000x per second alone in a single-cell. Errors in these  processes are typically checked and correctedâ¦ by special enzymes.  However errors in DNA transcription can result in protein synthesis  with deleted amino acids which at best can be harmless. At worst,  the deletion (or defective synthesis) of proteins can create fatal  cancers through localized cell mutations.
The transcription termination site is located after the ORF, beyond the translation stop codon, because if transcription were to cease before the stop codon, an incomplete protein would be made during translation. In eukaryotic genes with multiple exons, ORFs may span exons.
