What specific characteristics of yeast make it a “model organism” for study and the focus of so much research? Yeast are single-celled (unicellular) organisms, making them simple to study, but possess a cellular organization similar to that found in higher, multi-cellular organisms such as humans – that is, they possess a nucleus and are therefore eukaryotes, as described above.

1. Introduction. The causes of the poisonous properties of oxygen were obscure prior to the publication of Gershman’s free radical theory of oxygen toxicity in 1954, which states that the toxicity of oxygen is due to partially reduced forms of oxygen (Gerschman, Gilbert, Nye, Dwyer, & Fenn, 1954).In the same year, observations of a weak electron paramagnetic resonance (EPR) signal attributable.
