In a certain mutant strain of bacteria, an enzyme mistakenly attaches the amino acid isoleucine to tRNA 10% of the time instead of attaching the amino acid leucine. What will these bacteria synthesize?

A.
no proteins, because the inappropriately activated tRNAs will block translation
B.
proteins in which isoleucine is inserted at some positions normally occupied by leucine
C.
proteins in which leucine is inserted at some positions normally occupied by isoleucine
D.
no abnormal proteins, because the ribosomal translation machinery will recognize the inappropriately activated tRNAs and exclude them from the translation process
