Why are there only 45 different tRNA anticodons rather than 64 to match each of the mRNA codons?
A)The first nucleotide of a tRNA anticodon allows some flexibility or "wobble."
B)The second nucleotide of a tRNA anticodon allows some flexibility or "wobble."
C)The third nucleotide of a tRNA anticodon allows some flexibility or "wobble."
D)The remaining 19 tRNA anticodons are used for initiation and termination of protein synthesis.

The third nucleotide of a tRNA anticodon allows "wobble," meaning it can pair with more than one kind of nucleotide in the mRNA codon, reducing the need for a unique tRNA for each codon.
