What Happens To Introns And Exons After Splicing?

WebAll of a pre-mRNA’s introns must be completely and precisely removed before protein synthesis. If the process errs by even a single nucleotide, the reading frame of the rejoined exons would shift, and the resulting protein would be dysfunctional. The process of removing introns and reconnecting exons is called splicing. WebSpliced introns are stable and accumulated in the cells grown to the stationary phase. The postsplicing fate of intronic RNAs in vivo was investigated. The results of Northern blot analyses for total RNA prepared from cells before and after entry into the stationary phase are presented in Fig. Fig.3. 3.
