E. colion an LP: the power of CRISPR–Cas-mediated genome editing
This hand-colored scanning electron micrograph shows E. coli living on a phonograph record. These cells were engineered to express molecular components of the CRISPR–Cas system, enabling the cell to write a permanent record of the RNAs within the cell into its own genome, where it is safely stored. Scientists can retrieve the record and reveal the bacterium’s transcriptional history.
