Swiss scientists from the Federal Polytechnic School of Lausanne have discovered molecules that prevent cell aging. The RAD51 enzyme, which is involved in the restoration of damaged DNA, turns out to be the "

Reported by Nature.

Researchers studied TERRA molecules, a type of non-coding RNA that regulates telomere length and function.

TERRA accumulates at the ends of chromosomes, signaling that telomeres must be lengthened or repaired. Experts managed to find out that the RAD51 enzyme plays almost the main role in the attachment of TERRA to telomeres..

It is he who helps to restore damaged DNA molecules.

Due to the active work of this enzyme, a hybrid RNA-DNA molecule is formed.

Scientists have also found that short telomeres attract TERRA much more efficiently than long telomeres..

Telomeres are the end sections of chromosomes that protect DNA from damage during cell division, but at the same time their length is constantly reduced and prolongs youth.
