Recommendation

Scientists are exploiting their relatively new capabilities to read and write DNA. They make DNA markers that help them simultaneously study large numbers of samples – nanoparticles, cell types, drugs – in a way never before possible. But because everyone’s genetic information is still stored in DNA – that is, after all, its original purpose – storing other information in it is risky. Anyone with a sequencer could gain access to personal data. Read on to learn how putting information in DNA has been a boon for research, and why it’s is not quite yet ready to replace your hard drive. 

Take-Aways

  • DNA is extremely resistant.
  • Unique DNA bar codes have helped studies of drug delivery, drug resistance and disease development.
  • CRISPR has given chemical engineers the ability to write DNA sequences to record different types of information.
