Digital world vs the RNA world
• Digital bits: 2 states (0,1)• RNA bits: 4 states (U,C,G,A)
• Digital byte: 2^8 = 256 possibilities• RNA byte: ‘Codon’ 3 digits: 4^3 = 64
• BUT: Only 20 are used – 44 left for redundancy
Decoding
UCA, UCC, UCU, UCG+ AGU, AGC‘1 bit error correction)all code Serine
=> Even if you transmit UCA and UCC arrives at decoder -> still the right result
BUT:UGG is the only combination that leads to Tryptophan
