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.
A gene directs the synthesis of a protein by a two-step process. The first step is transcription of the gene in the DNA. Transcription produces a messenger RNA (mRNA) molecule. The second step is translation of the mRNA molecule. Translation produces a protein molecule. During transcription, the sequence of. nucleotides in a gene in the DNA is. copied to a corresponding sequence. of nucleotides in mRNA. During translation, the sequence of. nucleotides in the mRNA determines. the sequence of amino acids in the. protein.
