And when this is found inside that bacterial cell the bacterial cell will be able to use special types of proteins to transcribe the DNA into this premRNA but it will not be able to take out these RNA sections, these intron sections from this mRNA. And so because it's only these blue sections that are necessary to form that particular protein and because the bacterial cell has no way of removing these orange sections and splicing together the blue sections that bacterial cell will not be able to form any useful protein. Now the question is can we somehow fix this problem? Can we somehow create a eukaryotic gene that does not contain these intro sections, these intron sections here? Because if we can somehow create a Eukaryotic gene, if we somehow can take this Eukaryotic DNA and remove these introns just simply splice together the blue sections, then we'll form a gene that doesn't contain these useless intron sections. And then we take that gene, place it into that bacterial cell, and that bacterial cell won't have to worry about removing these introns, and so it can easily form that eukaryotic protein.
