Error-prone DNA replication and repair may lead to mutations and cancer in individuals who inherit a mutant copy of the BRCA1 gene, according to a new study by Weill Cornell Medicine investigators.

If they happen to do this just before the two DNA strands are cleaved as part of the cell replication process, the protons can become trapped on the wrong side, leading to a DNA mismatch and a ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

Error-prone DNA replication and repair may lead to mutations and cancer in individuals who inherit a mutant copy of the BRCA1 gene, according to a new study. The discovery has potential implications ...

The topographical features of DNA in the body may dictate where and when cancer-causing mutations appear in its code. When you purchase through links on our site, we may earn an affiliate commission.

Researchers at USC have developed a yeast model to study a gene mutation that disrupts the duplication of DNA, causing massive damage to a cell's chromosomes, while somehow allowing the cell to ...

The gene p53 acts as a tumor suppressor and often is called the ‘guardian of the genome.’ This gene is central to maintaining genomic stability, which prevents mutations from accumulating and leading ...

For 10% of colorectal cancer patients, hereditary factors play a role, with higher percentages among younger patients.
