What conclusion can be drawn if a transgene creates a stop codon within a coding sequence?

• A. The gene product will be synthesized normally
• B. The gene product will be incomplete
• C. The gene product will be functional
• D. The gene product will inhibit transcription

Answer: (B)

When a transgene introduces a stop codon within a coding sequence, it leads to the premature termination of the protein synthesis process. This means that the ribosome will halt translation when it encounters this stop codon, resulting in the production of an incomplete protein product. The incomplete protein may lack essential functional domains and will likely be non-functional because it does not have the full amino acid sequence that is required for it to carry out its biological role effectively. Therefore, the conclusion that arises from the presence of a stop codon within a coding sequence is that the gene product will indeed be incomplete.
