Question
A biologist inserted a gene from a human liver cell into the chromosome of a bacterium. The bacterium then transcribed this gene into mRNA and translated the mRNA into protein. The protein produced was useless; it contained many more amino acids than the protein made by the eukaryotic cell, and the amino acids were in a different sequence. Explain why.A biologist inserted a gene from a human liver cell into the chromosome of a bacterium. The bacterium then transcribed this gene into mRNA and translated the mRNA into protein.

Explanation / Answer
In humans , introns are spliced cut of the mRNA during protein synthesis ,
Where as in protein synthesis after insertion of inserted a gene from a human liver cell into the chromosome of a bacterium , introns are not spliced cut of the mRNA, leads to more amino acids with different sequence than the protein which is useless in bacteria.
