The D.N.A. is half the human genome and can cause cancer

Research has shown that uncoded DNA can interfere with the replication and recovery of our genome, resulting in the accumulation of mutations.

Previously, it was discovered that non-coded or repeated DNA pathers, "disgusting" DNA, account for about half of our genome and can disrupt the replication of the genome.

Researchers have described repeated DNA patterns as increasing during replication and increasing the risk of error in the genome, which may be an early cause of cancer.

Researchers believe that this work will help to improve the diagnosis and monitoring of some cancers, such as intestinal cancer, in which case errors in copying repeated DNA sequences are common: they point to progressing cancer.

The team found that when there was a replication of repeated DNA, the machine could not always copy the opposite DNA thread. This error could result in a halt to the replication and even a collapse of the replication mechanism.

DNA damage and subsequent genome instability contribute to cancer formation and progress, so research reinforces the link between "disturbing" DNA and cancer.
