In our previous episode, we discussed how cells handle single strand breaks and how they perform a quick but potentially error filled patch up of double strand breaks using Non-Homologous End Joining, or NHE J. Today, we're diving into the cell's high fidelity repair system for double strand breaks: Homologous Recombination, or HR. We'll explore how it works, why it's so accurate, and highlight the crucial roles played by proteins like BRCA 1 and BRCA 2.
