Can We Store Data In DNA? | DNA Digital Data Storage

The video explores the potential of DNA as a data storage medium, comparing its capacity to traditional digital storage. It explains DNA's structure and how digital data can be encoded into DNA. The process involves converting binary data into DNA sequences, synthesizing strands, and sequencing them to retrieve data. Challenges include error rates and the need for redundancy. Despite advancements, DNA storage is currently impractical for consumer use due to cost and speed. Future possibilities include storing data in living organisms using CRISPR and recombinases.
