Review Questions

• How do DNA data storage technologies convert digital information into a format suitable for DNA synthesis?
  • DNA data storage technologies convert digital information into sequences of nucleotides by encoding binary data as combinations of the four DNA bases (adenine, thymine, cytosine, and guanine). This encoding process allows for the representation of digital files in a biological format that can be synthesized into actual DNA molecules. Once synthesized, this DNA can be stored in a stable state, allowing for long-term preservation of the encoded information.
• Discuss the advantages of using DNA for data storage compared to traditional methods like magnetic or optical media.
  • Using DNA for data storage offers several key advantages over traditional methods. Firstly, DNA provides an exceptionally high data density; it can store vast amounts of information in a tiny physical space. Additionally, DNA is incredibly stable over time, capable of lasting for millennia when stored correctly, whereas magnetic and optical media can degrade within decades. Lastly, the rapid growth of digital data worldwide presents challenges for conventional storage solutions, making DNA's compact nature and longevity an attractive alternative.
