A tRNA molecule produced in a laboratory has the anticodon for the amino acid serine,but carries the amino acid leucine.When it reaches the serine codon on a molecule of mRNA where translation is under way,what is the most likely outcome?
A) It will not bind with the codon on the mRNA molecule.
B) A potentially dysfunctional protein will result.
C) A proofreading enzyme will change leucine to serine.
D) Translation will stop.

The tRNA molecule carrying the wrong amino acid will insert the wrong amino acid into the growing polypeptide chain, resulting in a potentially dysfunctional protein. Translation will not necessarily stop, as there are other tRNA molecules with the correct anticodons and amino acids available to continue the synthesis of the protein.

A TRNA Molecule Produced in a Laboratory Has the Anticodon
