An experimenter has altered the 3' end of the tRNA corresponding to the amino acid methionine in such a way as to remove the 3' bases AC. Which of the following hypotheses describes the most likely result?
A) tRNA will not form a cloverleaf.
B) The amino acid methionine will not become covalently bound.
C) The anticodon will not bind with the mRNA codon.
D) The aminoacyl-tRNA synthetase will not be formed.

The 3' end of tRNA molecules contains the CCA sequence that is necessary for the covalent attachment of the amino acid. Without these bases, the amino acid methionine will not become covalently bound to the tRNA and will not be incorporated into a growing polypeptide chain during translation.
