According to Futuyma (2005, p. 172), "with such a low mutation rate per locus, it might seem that mutations occur so rarely that they cannot be important.
We study the evolution of clonal populations where the mutation input is large (NU≫1) and both beneficial and deleterious mutations occur, so we study FGM under intense CI.
In the present model, it is assumed that nucleotide mutations occur independently at each codon position and so any double nucleotide mutation occurs as frequently as doublet mutations.
Experimentation showed that wild types virtually never went extinct after a mutation event had occurred; so, runs with mutation events were counted as successful, even though they were usually aborted if the mutants subsequently went extinct.
The most frequent site of mutation occurs to the so-called gatekeeper residue which is located towards the rear of the ATP-binding cleft.
Its genetic mutation occurs on the X chromosome, so women are typically carriers, while their sons suffer the disease.
On the other hand, recurrent mutation occurs one site at a time, so that it is unlikely to observe inconsistent sites clustering together in a long range.
Each F1 fish carries a unique set of heterozygous ENU-induced mutations, so any given mutation occurs only once in the entire library, i.e. at a ratio of 1 mutant: 18,048 WT alleles.
In this study, we only investigated the SQSTM1/P392L mutation, the most common mutation associated with PDB so far, since this mutation occurs at a hypermutable CpG dinucleotide sequence, a mutational hotspot (Laurin et al. 2002; Morissette et al. 2006).
Design the primers so that the desired mutation occurs at the center of the primer.
