When a region of DNA that contains the genetic information for a protein is isolated from a bacterial cell and inserted into a eukaryotic cell in a proper position between a promoter and a terminator, the resulting cell usually produces the correct protein. But when the experiment is done in the reverse direction (inserting the eukaryotic DNA into the bacterial cell), the correct protein is not produce. Why is this the case?

Explanation:

Eukaroytes are orgamsims with membrane bound organelles

In eukaryote, the DNA sequence contains introns (which are the non-coding part of the DNA that should be removed through a process called splicing) which cannot be spliced out properly by the bacterial cell and therefore resulting in protein other than the initial template(Incorrect protein) reading from the information in the bacterial RNA(ribonucleic acid)transcript. For Eukaryotes with correct protein the introns are spliced properly and corresponding amino acids or protein are formed in ordered succession leading to a correct protein.
