Will Splicing Occur in Prokaryotes?

In prokaryotes, splicing is a rare event that occurs in non-coding RNAs, such as tRNAs (22). On the other hand, in eukaryotes, splicing is mostly referred to as trimming introns and the ligation of exons in protein-coding RNAs.

Is splicing absent in prokaryotes?

The remaining regions that are translated are called exons, and the process of intron removal and exon fusion is called splicing. ... No evidence of these introns has been found in prokaryotes despite the sequencing of more than 100 genomes (Lynch and Richardson, 2002).

Can prokaryotic mRNA be spliced?

Both prokaryotes and eukaryotes process their ribosomal and transfer RNAs. The major difference in RNA processing, however, between prokaryotes and eukaryotes, is in the processing of messenger RNAs. ... The process of removing the introns and rejoining the coding sections or exons, of the mRNA, is called splicing.
