How stable is arsenic DNA?

Best Answers

Measurements on arsenic DNA analogs made by researchers several months later found that the arsenic analogs differed in stability from their phosphate versions by a mind-boggling factor of 1017. read more

The idea/proofs of arsenic DNA has been highly refuted by the scientific community. The data published by this group was not reproducible. Also, when the experiments were done at phosphorous concentration lower than that used in the study, bacteria failed to thrive. read more

The chemists were quite confident in extrapolating from these simple cases to questioning the stable existence of arsenic DNA; if arsenic DNA indeed were so stable, then almost everything they had known about arsenate esters for fifty years would have been wrong, a possibility that was highly unlikely. read more

Contrary to accepted wisdom, scientists claim that arsenic could replace phosphorus in the DNA backbone and remain stable in water In 2011, a paper published in Science claimed that bacteria from Mono Lake, California, US, had not only evolved to tolerate arsenic, but had incorporated it into their DNA. read more

Researchers at UPM have studied the stability of diverse arsenic species found in edible marine algae and have established the best conditions for their storage and preservation. read more
