The number of tRNA molecules is smaller than the number of codons due to wobble pairing
the verdict
SUPPORTED
the evidence backs this
confidence 75/100
The number of tRNA molecules is smaller than the number of codons because wobble base pairing allows single tRNAs to recognize multiple synonymous codons.
