Sl1 binding to pre mrna c. elegans
WebIn C .elegans, the splicing of the sequence leader occurs close to the initiation codon. Some scientists also suggest the sequence is required for cell viability. In Ascaris, the spliced leader sequence is needed to the RNA gene can be transcribed. WebSL1 leaders are spliced mostly to pre-mRNAs from genes with outrons, intron-like sequences at the 59-ends of the pre-mRNAs. In contrast, SL2 leaders are nearly …

WebPolycistronic pre-mRNAs from Caenohabditis elegans operons are processed by internal cleavage and polyadenylation to create 3' ends of mature mRNAs. This is accompanied by trans-splicing with SL2 approximately 100 nucleotides downstream of the 3' end formation sites to create the 5' ends of downstream mRNAs. WebC. elegans represents an especially favorable system to study the extraordinarily complicated process of eukaryotic protein synthesis, which involves over 100 RNAs and over 200 polypeptides just for the core machinery.
