【正文】 s evolved in an arsenicrich environment, is the first terrestrial lifeform found which may have this ability. The bacterium was found in Mono Lake, east of Yosemite National Park. GFAJ1 is a rodshaped extremophile bacterium in the family Halomonadaceae that, when starved of phosphorus, may be capable of incorporating the usually poisonous element arsenic in its DNA.[41] This discovery may lend weight to the longstanding idea that extraterrestrial life could have a different chemical makeup from life on Earth.[41][42] The research was carried out by a team led by Felisa WolfeSimon, a geomicrobiologist and geobiochemist, a Postdoctoral Fellow of the NASA Astrobiology Institute with Arizona State University. This finding has, however, faced strong criticism from the scientific munity。在同一股脫氧核糖核酸上，可能同時會有屬于正意和反意的片段。往 339。 樣例文本 C ? 一般來說，當(dāng)一段脫氧核糖核酸序列為合成信使 RNA（ mRNA，可轉(zhuǎn)譯成蛋白質(zhì)）所需時，稱為“正意”。此外，反意 RNA在原核生物或真核生物體內(nèi)皆存在，但是其功能尚未明了 [21]。的方向合成蛋白質(zhì)，另一方面也能以相反方向合成另一
