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.
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.NA replication is not perfect. Errors occur in DNA replication, when the incorrect base is incorporated into the growing DNA strand. This leads to mismatched base pairs, or mispairs. DNA polymerases have proofreading activity, and a DNA repair enzymes have evolved to correct these mistakes.
