Mismatch Repair

Mismatch Repair (MMR) is a natural process inside our cells that corrects errors made during DNA copying before cell division. When cells divide, mistakes can happen, like improperly paired or missing bases, which could lead to mutations. MMR detects these errors, retrieves the faulty section, and accurately repairs it to maintain DNA integrity. This process is vital for preventing genetic mutations that can cause diseases like cancer. Essentially, MMR acts as a quality control system, ensuring the genetic information is copied correctly and preserved across generations of cells.
