A researcher is studying translation in a prokaryotic cell. They introduce a modified mRNA where all the guanine nucleotides in the coding sequence are replaced with inosine. Which of the following is the MOST LIKELY effect on translation?
Translation will terminate prematurely due to the presence of inosine.
The ribosome will be unable to bind to the modified mRNA.
The protein synthesized will be identical to the one produced from the unmodified mRNA.
The protein synthesized will have altered amino acid sequence due to changes in codon recognition.
