Mutation
... DNA can give rise to one of nine other codons. Two of the possible changes (CUA , UUG) are completely silent, as the resulting codons still code for leucine. These are known as synonymous codons. Two further changes (AUA and GUA) may well have little effect on the protein since the substituted amino ...

The Genetic Basis for Evolution: Genetic Variation
... Recall that our genetic code is rooted in molecules of DNA. DNA is itself a long chain of component molecules called nucleotides, whose initials are A, T, G, & C. As with Morse code and the alphabet, the secret to the genetic code lies in the SEQUENCE of its components …the sequential order of those ...

... Schmidhauser et al. (1999) reported that un-4 was on a cosmid with lys-5, we attempted to complement the un-4 lesion using cosmid G13:G8 from the Orbach Sachs pMOcosX library (Orbach and Sachs, 1991; Vollmer and Yanofsky, 1986). While this cosmid was reported to complement un-4 (Schmidhauser et al., ...
Epistasis
Epistasis is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually. It was originally a concept from genetics but is now used in biochemistry, population genetics, computational biology and evolutionary biology. It arises due to interactions, either between genes, or within them leading to non-additive effects. Epistasis has a large influence on the shape of evolutionary landscapes which leads to profound consequences for evolution and evolvability of traits.
