AMBIGUITY OF THE TRANSCRIPTION BOUNDARIES OF EUCARYOTIC GENES
A great number of experimental data testify to a more complicated -mechanism of the eucaryotic mRNA generation as compared to that of procaryotic mRNAs. The latter have a transcription process which begins and terminates in the sites corresponding to 5'- and 3'-ends of functional mRNAs. The nuclear cells appear to have special control mechanisms of differential gene expression by selecting sites for initiation and termination of the transcription and/or for polyadenylation of mRNAs.
