Open Reading Frames * (ORFs) are regions with no stop codons. All genes reside in long open reading frames * Note that stop codons in other reading frames have no effect on the gene. * Can be searched in the genome sequence. Valid only for prokaryotes and lower eukaryotes. Protein Sequencing vs. DNA sequencing * We compare protein sequences‚ not DNA‚ because protein is more conserved in evolution than DNA * The organism’s survival depends on the protein being
