"We thought it would take roughly a million years for bacteria to evolve enzymes capable of digesting nylon ( because the compound is so different than any they were able to digest ) but it took less than a century . ."
"Were they able to show a previously non-existing code that mutated on a gene somewhere and created this new enzyme activity ? It sounds to me that this `` new `` enzymatic activity came from non-coding dna switching on a gene to produce it . That is what one would expect to find . ... * Two new enzyme activities , 6-aminohexanoate cyclic dimer hydrolase and 6-aminohexanoate dimer hydrolase , were detected in the adapted strains . * ..."
