Final answer:
The adaptor hypothesis indicates that tRNA anticodons recognize mRNA codons with wobble; amino acids attached to tRNA do not recognize mRNA codons but are crucial for protein synthesis, and the binding of tRNA to mRNA codons is determined by anticodon-codon interactions, not by the attached amino acid.
Step-by-step explanation:
According to the adaptor hypothesis, statement A is true: the sequence of anticodons in tRNA directly recognizes codon sequences in mRNA, with some allowance for wobble.
Statement B is false: the amino acid attached to the tRNA does not directly recognize codon sequences in mRNA. Instead, it is the anticodon of the tRNA that matches with the codon on the mRNA. Lastly, statement C is false: while the attachment of the amino acid is crucial for protein synthesis, it is not involved in the binding specificity of the tRNA to a codon sequence in mRNA.
This specificity is determined by the anticodon-codon interaction. tRNAs serve as adaptors in protein synthesis, translating the mRNA nucleotide code into a polypeptide sequence by bringing the correct amino acids to the growing polypeptide chain based on the code.
