Although 61 different codons code for amino acids, cells contain fewer than 61 different tRNAs. Why?
A. Although 61 different codons code for amino acids, any given cell contains fewer than 61.
B. Because the 5' base on the mRNA codon has some flexibility (wobble); thus, some mRNA codons can pair with more than one tRNA anticodon.
C. Because the 5' base on the tRNA anticodon has some flexibility (wobble); thus, some tRNA anticodons can pair with more than one mRNA codon.
D. Because each amino acid is coded for by just one codon.
