|Title:||A unique group of self-splicing introns in bacteriophage T4|
|Authors:||Khan, Asad U|
|Abstract:||We describe in this review, the salient splicing features of group I introns of bac teriophage T4 and propose, a hypothetical model to fit in the self-splicing of nrdB intron ofT4 phage. Occurrence of non-coding sequences in prokaryotic cells is a rare event while it is common in ellkaryotic cells, especially the higher eukaryotes. Therefore. T4 bacteriophage can serve as a good model system to study the evoluti onary aspects of splicing of introns. Three genes of T4 phage were found to have st retches of non-coding sequences which belonged to the group IA type introns of self-splicing nature.|
