An analysis of the origin of adaptive mutations in saccharomyces cerevisiae
We performed a 1012-generation mutation-accumulation (ma) experiment in the yeast, saccharomyces cerevisiae the ma lines exhibited a significant reduction in mean fitness and a significant increase in variance in fitness we found that 575% of the fitness-altering mutations accumulated were beneficial. Calcineurin is a heterodimer of catalytic subunit and regulatory subunits in the yeast saccharomyces cerevisiae, the catalytic subunit is encoded by two genes, cna1 and cna2 , whereas a single gene, cnb1, encodes the regulatory subunit cells lacking the catalytic subunits, or the regulatory subunit, are deficient in calcineurin activity. 1 comparative genome analysis of saccharomyces cerevisiae 2 yeasts isolated from traditional fermentations unveils 3 that adaptive mutations include not.

Molecular studies have shown that adaptive mutations include not just the generation of new alleles by nucleotide substitution (cubillos et al, 2011 salinas et al, 2012), but also gene duplication (barrio et al, 2006) and other genome rearrangements (pérez-ortín et.
