New york: : Researchers at the University of California claim to have discovered a new system to encode digital information within DNA. According to the researchers, this method relies on length of the fragments obtained by the partial restriction digest rather than the actual content of nucleotide sequence, the Langmuir medical journal has reported. "What we developed is a method to encode a message in DNA in a way that does not require an expensive sequencing machine. The decoding still requires a wet lab procedure, but the experimental procedure is significantly easier,' said lead researcher Prof Stefano Lonardi. But, why is this discovery important? Well, the human genome consists of the equivalent of approximately 750 MB of data
