NHEJ (Non-Homologous End Joining)

Non-Homologous End Joining (NHEJ) is a process our cells use to repair broken DNA strands. When DNA, which carries our genetic information, breaks suddenly, NHEJ quickly mends the break by directly joining the broken ends together. It doesn't require a matching template or copy, so it’s faster but can sometimes make small errors at the repair site. This mechanism is essential for maintaining genetic stability, especially in response to damage from radiation or other stressors. Overall, NHEJ helps keep our cells functioning properly by efficiently fixing DNA damage, although it can occasionally lead to mutations.
