CAC both code for histidine; in both, the third base, U (uracil) or C (cytosine), is a pyrimidine. Only two of the families of codons are split differently. The lesser importance of the third position in the genetic code ties in with two facts about transfer RNAs. First, although there would seem to be a need for sixty-two transfer RNAs since there are sixty-one codons specifying amino acids and an additional codon for initiation there are actually only about fty different transfer RNAs in an E. coli cell. Second, a rare base such as inosine can appear in the anticodon,usually in the position that is complementary to the third position of the codon.These two facts lead researchers to believe that some kind of conservation of transfer RNAs is occurring and that rare bases may be involved. We should mention, to avoid confusion, that both messenger RNA and transfer RNA bases are usually numbered from the 5 side.Thus, the number-one base of the codon is complementary to the number-three base of the anticodon ( g. 11.32).Thus, the codon base of lesser importance is the number-three base, whereas its complement in the anticodon is the number-one base. Since the rst position of the anticodon (5 ) is not as constrained as the other two positions, a given base at that position may be able to pair with any of several bases in the

third position of the codon. Crick characterized this ability as wobble ( g. 11.33).Table 11.5 shows the possible pairings that would produce a transfer RNA system compatible with the known code.For example,if an isoleucine transfer RNA has the anticodon 3 -UAI-5 , it is compatible with the three codons for that amino acid (see table 11.4): 5 -AUU3 , 5 -AUC-3 , and 5 -AUA-3 .That is, inosine in the rst (5 ) position of the anticodon can recognize U, C, or A in the third (3 ) position of the codon, and thus one transfer RNA complements all three codons for isoleucine.

Universality of the Genetic Code
Until 1979, scientists concluded that the genetic code was universal. That is, the codon dictionary (see table 11.4) was the same for E. coli, human beings, and oak trees, as well as all other species studied up to that time.The universality of the code was demonstrated, for example, by taking the ribosomes and messenger RNA from rabbit reticulocytes and mixing them with the aminoacyl-tRNAs and other translational components of E. coli. Rabbit hemoglobin was synthesized. In 1979 and 1980, however, researchers noted discrepancies when sequencing mitochondrial genes for struc-

tural proteins (see chapters 13 and 17). It was discovered that there were two kinds of deviations from universality in the way mitochondrial transfer RNAs read the code. First, fewer transfer RNAs were needed to read the code.Second, there were several instances in which the mitochondrial and cellular systems interpreted a codon differently. According to Crick s wobble rules (see table 11.5), thirty-two transfer RNAs (including one for initiation) can complement all sixty-one nonterminating codons. Unmixed families require two transfer RNAs, and mixed families require one, two, or three transfer RNAs, depending on the family.The yeast mitochondrial coding system apparently needs only twenty-four transfer RNAs.The reduction in numbers is accomplished primarily by having only one transfer RNA recognize each unmixed family
