WOBBLE HYPOTHESIS - Jiwaji University
The Wobble Hypothesis •The first two bases of the codon make normal (canonical) H-bond pairs with the 2nd and 3rd bases of the anticodon •At the remaining position, less stringent rules apply and non-canonical pairing may occur •The rules: first base U can recognize A or G, first base G can

Wobble Base Pairing Hypothesis •The wobble hypothesis provides insight into some aspects of the degeneracy of the code –in many cases, the degenerate codons for a given amino acid differ only in the third base; therefore fewer different tRNAs are needed because a given tRNA can base-pair with several codons –the existence of wobble
Beyond the Wobble: The Rule of Conjugates
a molecular basis for the nature of the observed wobble The wobble hypothesis allows for G U base pairing at the third position of the codon in addition to the usual Watson-Crick G C and A U pairing, laying out a mecha-nism for the realization of the degeneracies An alterna-tive explanation for some of the observed degeneracies

Crick proposed the Wobble hypothesis to generalize Holley’s observation: - Interaction between codon and anticodon need to be exact at first two positions - The third interaction can be less restrictive, and can include non standard base-pairing This hypothesis accounts for the degeneracy In the Genetic Code The wobble hypothesis (Crick, 1966)
MODULE 7: GENE, GENOME AND GENE EXPRESSION
According to the Wobble hypothesis, the third position of a codon is often interchangeable For example: GCU codes for alanine and so does GCC tRNA with anticodon CGG can bind to this codon and bring alanine

wobble position affect the codon recognition properties of the tRNA and are essential for the accurate and complete reading of the genetic code [2] The wobble hypothesis was proposed by Crick to account for the obser-vation that most organisms code for considerably fewer tRNAs than the number of sense codons, precluding a sim-
Role of taurine in the pathologies of MELAS and MERRF
Wobble hypothesis of MELAS The Wobble hypothesis of MELAS traces the respiratory defects to inefficient decoding of the UUG codon According to the wobble hypothesis, the A3243G mutation interferes with the conjugation of taurine with a wobble position uridine of tRNALeu(UUR), a reaction that stabilizes
MODERN CONCEPT OF GENE - WordPresscom
The wobble hypothesis was proposed by Crick (1965), which states that the first two nitrogenous bases of the triplet codon pair according to set rule, i e , A with U, G with C but the third base has much more freedom of pairing The wobble base permits more than one type of pairing
TRANSCRIPTION, TRANSLATION & THE GENETIC CODE
The Wobble Hypothesis • Theoretically need 61 tRNAs –Actually have: •30-40 in prokaryotes •50 in eukaryotes • Fewer tRNAs than codons • “Relaxed” base pairing allows 1 tRNA to bind multiple codons but still deliver correct amino acid
