These tables provide information about how frequent each nucleitide triplet is seen in a large sample of E. Coli gene sequences. For your homework, please use the table in the bottom (i.e., the table with 5 columns). The numbers in the 3rd column are the raw counts of each triplet. E.g., the count of "GGG" is 17704 and that of "TTT" (="UUU") is 35982. These numbers can be normalized to obtain probabilities of seeing each triplet, which are given as the 4th column. E.g., the probability of seeing "GGG", p("GGG") is 11.01/1000 = 0.01101. The 5th (fraction) column gives the probability that an amino acid is seen to be encoded by a particular triplet. Note that the same amino acid can be encoded by several triplets; some of them are more frequently used than others. E.g., the amino acid "Asp" is more frequently coded by "GAT" (63%) than by "GAC" (37%).
