On the road to immortality: important age genes are found

Scientists from the University of Exeter (UK) have identified a group of genes that play a key role in the aging process.

In particular, they regulate the cleavage factors – molecules that determine the way in which information RNA ripens, reports MedicalXpress.

Splicing refers to the process of excision of nucleotide sequences (introns) from the RNA molecule and cross-linking of the remaining (exons), resulting in the maturation of the molecule.

Thus, introns do not carry information about the amino acid sequence of the polypeptide (protein). Sometimes there is an alternative split, when exons are removed or introns remain, allowing the same gene to code for different polypeptides. An important role here is played by spliceosomes – complexes of RNA and proteins.
