... A mutant strain with the UUU codon (phenylalanine) may undergo a further mutation which restores the UUA codon (a true back mutation) The effect of a mutation can also be negated by a second, unrelated mutation; this effect is known as suppression. There are two types of suppression that are of ...

Because 5´-UAA-3´ does not contain G or C, a transition to a GC pair in the DNA cannot result in 5´-UAA-3´. 5´-UGA-3´ and 5´-UAG-3´ have the DNA antisense-strand sequence of 3´-ACT-5´ and 3´-ATC-5´, respectively. A transition to either of these stop codons occurs from the nonmutant 3´ATT-5´. Howe ...
