Synonymous nucleotide
WebSynonymous single-nucleotide polymorphisms within the same gene can create individual variations in translation speeds, leading to dramatic effects on protein folding between individuals. A striking example of this kind concerns multidrug resistance 1 ( MDR1 or ABCB1 ) gene ( 105 , 106 ). http://www.als-journal.com/10122-23/
