The finding includes the useful insight that the cold virus can be stopped by targeting a key viral enzyme in just the right way. (sciencedaily.com)
The swap was done by placing bacterial cells in a water bath with viral enzymes and fragments of single - stranded DNA. (newscientist.com)
They then designed fragments of single - stranded DNA that, with the assistance of viral enzymes, would replace the TAG stop codons with TAA, another stop codon. (newscientist.com)
