CCCGATATTACGCTTAGGTACCGTC Every 3 bases code for one amino acid! (See board) DNA & Evolution Chimpanzees and Humans share 98-99% of their DNA! CCCGTCAGGCTAATACGAGCGGT CCCGTCGGGCTAATACGAGCGGT DNA & Evolution Who can read the human genetic code? The genetic code is UNIVERSAL! Practical Implication: Genetic engineering: Bacteria are programmed with HUMAN insulin gene to produce………….?
