The other aspect of this problem lies in defining mismatch acceptance within motif hits, which would allow regarding mutations occurring in evolutionary processes, such as SELEX.
At the molecular level, the fixation of mutations in an evolutionary lineage (i.e., substitution events), is a complex dynamic process determined by the interaction between evolutionary (selection) and demographic (drift) forces [ 8].

Following Morgan's work, molecular studies indicated the importance of random mutation in the evolutionary change of DNA.
The primary mechanism of this dysfunction in ovarian cancer is a missense mutation in the evolutionary conserved domains of the gene.
I show first, that incorporating neutral mutations significantly increases the number of point mutations in a given evolutionary walk when compared to estimates from previous adaptive walk models.
Unlike traditional SCA (statistical coupling analysis) approach [2], [15], [16], [17], which is based on the statistical analysis of position conservations, the CMCA focuses on the correlations of position mutations in a protein evolutionary family.
Therefore, lacking the MBD4 gene in sea squirts could have resulted in a large number of CpG mutations in a short evolutionary history, and then the new TpG sites in sea squirt genes drive a strong negative selection against the following A nucleotides due to the potential to form a stop codon.
Prior studies have anecdotally demonstrated the existence of such mutations in natural protein evolutionary paths.
