, and the research team's lead scientist. “If something here on Earth can do something so unexpected, what else can life do that we haven't seen yet?”During the press conference, Wolfe-Simon explained that the reason arsenic is so toxic to normal life, is that it's so close to phosphorus our bodies can't tell them apart.”Nothing replica DKNY NY3916 WoMen's watch should have grown,” she said of the environment of Lake Mono. Yet it did. “It has solved the challenge of being alive in a very different way than we knew of.”The arsenic is associated specifically with a band of genomic DNA. It's inside the cell. It's part of the microbe, taking the place of phosphorus.
Arizona State University's Dr. James Elser explained that the existence of an organism that does without phosphorus has far-reaching possibilities. “It's very exciting to think about the possibilities of a clever organism that's evolved beyond using phosphorus,” said Elser after explaining how vital the element is to life on Earth. He marveled replica DKNY NY3928 WoMen's watch over the possible uses for such an organism, including water treatment, bio-energy production, and even recovering phosphorus used in other processes.Dr. Steven Benner of the Foundation for Applied Molecular Evolution put things in layman's terms.
Using a steel chain to represent a phosphorus bio-polymer, he likened arsenic to a tinfoil link. When a link is broken it searches for a replacement, and the chain could be confused by the similar structure of arsenic. He called the element a demon wolf, tricking organisms into taking it it.”Remember, the weakness of the link is a weakness replica DKNY NY4229 WoMen's watch measured at room temperature...in water,” Benner said. There are places in our own solar system where the conditions are very different that could support another sort of life entirely, as is the case with Lake Mono and GFAJ-1.NASA astrobiologist Dr. Pamela Conrad spoke next.
