What is the \'wobble\' position? What is the consequence of its presence? Solution Answer : During intercation between mRNA/codons and tRNA/anticodons, The third base of the codon and the first base of the anticodon constitutes the wobble position. Wobble Allows Some tRNAs to Recognize More than One Codon. This is due to the fact that strict watson and crick base pairing rules applies only to the first two bases of the codon where as third base tRNA can recognise more than one codon..
