Question

Which of the following procedures would be LEAST likely to prevent bacterial synthesis of the superantigen protein? A. Adding tRNA nucleotides that can bind to mRNA and bacterial ribosomes B. Adding a repressor protein that binds to the operator site of the bacterial superantigen gene C. Adding a specific complementary nucleic acid sequence that can bind to mRNA transcribed from the superantigen gene D. Adding a stop codon within the bacterial superantigen gene 2016 Association of American Medical Colleges (AAMC). All rights reserved. May not be reproduced without prior written permission.

Explanation / Answer

The least likely approach to prevent superantigen synthesis would be

Option A i.e. adding tRNA nucleotides that can bind to bacterial mRNA and ribosomes

Reason : Addition of tRNA nucleotides will aid in translation process and hence will favour the synthesis of superantigen protein rather than preventing the synthesis.
