George Church and Sri Kosuri , Wyss Institute scientists from Harvard, wrote a scientific publication where they explain their method for recording data petabits 5.5 molecules. For this, strips synthesized nucleic acid capable of storing 96 bits using hydrogenated bases to represent a binary value, where thymine (T) and guanine (G) are each, and adenine (A) and cytosine (C) zero.

To read the recorded Information in the DNA sequence, as it is performed when the human genome, and converts binary base ACGT. To assist sequence it, DNA strand starts with an address block of 19 bits ordering information.

Scientists have been long enough aware of the capabilities of DNA to store information because of its high density (as each bit represents a hydrogen-based and only a few atoms long), because it is volumetric rather than flat and incredibly stable, because its degradation takes years .

While DNA sequencing takes its good hours, no less impressive than that amount of information can be stored in only one gram of weight, where scientists calculated that to save the 5.5 petabits able to store information that you would need 233 hard drives 3 terabytes, which would add 151 kilos.
