1. Biological Coding Theory DNA: Source Code RNA: Object-File Protein: Executable/Running Code

2. Slide with Channel Schematics DNARNA------------------------ AminoAcid ->Protein

3. 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

4. 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

5. More failover preventions DNA Helix is redundant in itself – similar to a RAID1 system two copies of each chromosome
