Neural networks taught to search for damaged DNA


Neural networks begin to examine human DNA andtrack damaged areas due to ultraviolet radiation. The application of such a technique was proposed by an international group of scientists who believe that computer diagnostics will allow us to establish a relationship between DNA damage and ultraviolet radiation that causes cancer.

The study was conducted on test smallDNA sections (oligonucleotides) with different sequences, which were irradiated with ultraviolet light for different times. Analysis of the damage was carried out on a Raman spectrometer, and the obtained data were used to train neural networks.


Trained neural networks help scientists identify andpredict damage to the DNA chain from ultraviolet radiation. In addition, neural networks using Raman spectroscopy data more accurately than conventional methods diagnose changes in the DNA chain. Such a technique will improve the accuracy of medical diagnostics.
