Research article Quantitative transciptome, proteome, and sulfur metabolite profiling of the Saccharomyces cerevisiae response to arsenitecan be found here

1. Chelation: the combination of a metal ion with a chemical compound, forming a ring [1]
2. Northern blot analysis: used to separate and identify RNA fragments; transfers RNA from an agarose gel to a nitrocellulose filter followed by probe detection [2]
3. Ortholog/orthologous:genes or proteins found in different species that are so similar in their amino acid sequences that they are assumed to have originated from a single ancestral gene [3]
4. Permease: a membrane-bound protein in bacteria that is responsible for transport of a specific substance in or out of the cell [4]
5. Ubiquitination: the post-translational modification of one or more ubiquitin monomers (regulatory proteins) by covalent attachment [5]

Journal Outline
