... FEBS 2041 sequence and plotted the distribution of its length (see the Materials and methods for details). The lengths were normalized for every protein cluster and then averaged for evaluation. ... sequence termini. Therefore, we tentatively propose that the insertions of new transcription start and stop codons, as well as gene fusion and fission, are more likely to occur than...
