Episode notes
DNA Data Storage
- DNA can store digital information like hard drives, using A, C, T, and G.
- Each cell holds about 1GB, totaling 30 trillion GB in a human body, enough for one-fifth of the world's data.
DNA Information Storage
- DNA stores information as a sequence of A, C, T, and G letters.
- These letters are converted into binary code (0s and 1s) for digital storage (A=00, T=01, G=10, C=11).
DNA Computing
- DNA can process information using enzymes or molecular interactions.
- Enzymes can target specific DNA sequences, while molecules can bind/unbind for logical operations.
