The human B-globin gene contains introns which the bacterial cells cannot remove. This leads the bacterial cell to try to translate the introns, which include stop codons which truncate the protein.

Work Step by Step

This question is asking you to compare bacterial and eukaryotic gene expression and find key differences: skim the chapter and make a list of the differences. Genetic code may be universal, but prokaryotes have a different overall organization that makes their processes dramatically different from those of eukaryotes. Use your imagination to see which one would lead to protein truncation-- introns that are automatically removed in eukaryotes will not be by the prokaryotic mechanism, which is one of the most likely issues in the given scenario.
