If only the nucleotide sequence were screened, it would have been easy for ill-intentioned people to bypass the software: modifying the DNA sequence such as the sequence doesn't mime the dangerous one, but in having the same resulting amino-acid chain. Changing each triplet of nucleotides by a different one but coding for the same amino-acid is enough to obtain such a result.
