New instruction manual discovered for repairing broken DNA

Drexel University and Georgia Institute of Technology researchers have discovered how the Rad52 protein is a crucial player in RNA-dependent DNA repair. The results of their study, published in Molecular Cell, reveal a surprising function of the homologous recombination protein Rad52. They also may help to identify new therapeutic targets for cancer treatment.
Radiation and chemotherapy can cause a DNA double-strand break, one of the most harmful types of DNA damage. The process of homologous recombination — which involves the exchange of genetic information between two DNA molecules — plays an important role in DNA repair, but certain gene mutations can destabilize a genome. For example, mutations in the tumor suppressor BRCA2, which is involved in DNA repair by homologous recombination, can cause the deadliest form of breast and ovarian cancer. Paper.

Darwinism is beyond ridiculous and the only solution now is retirements.
