Description:
Wolfe-Simon et al. (Research Articles, 3 June 2011, p. 1163; published online 2 December 2010) reported that bacterial strain GFAJ-1 can substitute arsenic for phosphorus in its biomolecules, including nucleic acids and proteins. Unfortunately, their study lacks crucial experimental evidence to support this claim and suffers from inadequate data and poor presentation and analysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Csabai, Istvan -- Szathmary, Eors -- New York, N.Y. -- Science. 2011 Jun 3;332(6034):1149; author reply 1149. doi: 10.1126/science.1201399.
