spliceosomal complexes

Spliceosomal complexes are molecular machines within cells that process precursor messenger RNA (pre-mRNA) by removing non-coding regions called introns. This process, known as splicing, is essential for generating mature mRNA that can be translated into proteins. The spliceosome is made up of small RNA and protein components that assemble in a precise sequence, recognize specific RNA signals, and catalyze intron removal. This ensures that only the relevant, coding parts of the RNA are preserved for protein synthesis, playing a crucial role in gene expression and diversity.
