If mutations confer a proliferative advantage, mutated cells can bypass the in vitro lifespan limit and rapidly replace the existing population [ 14, 15].
Specificity is effectively shown empirically by testing if mutations blocking target activity remove cellular inhibitor impact.
And so if mutations happen, they can be erased at the stage of genome assembly during development.
To determine if mutations in NELF, a gene isolated from migratory GnRH neurons, cause normosmic idiopathic hypogonadotropic hypogonadism (IHH) and Kallmann syndrome (KS).
More specifically, a link (or edge) is placed between a disorder and a disease gene if mutations in that gene will lead to the specific disorder.
If mutations occur as a result of errors during cell division, the model suggests that a low cellular turnover rate protects both against aging and the development of cancer.
Thus, if mutations occur sequentially, the shape of the fitness landscape may prevent evolution of the optimal phenotype [7, 8] offering a possible explanation for the poor discrimination of receptors found in nature.
On the other hand, if mutations occur independent from cell division (e.g. if DNA is hit by damaging agents), I find that a high cellular turnover rate protects against aging, while it promotes the development of cancer.
If mutations occur randomly (i.e. none is favored by selection), most sequence variants (haplotypes) will each appear in only a few individual plants.
Changes in regulation of protein expression, loss of function of a cell, or even uncontrollable division can occur if mutations in cellular DNA go uncorrected.
This high frequency of mutations could, however, impede our antibody identification if mutations occurred in PCR primer-binding sites.
