Plaque hybridization

Plaque hybridization is a molecular biology technique used to detect specific DNA or RNA sequences within a mixture of nucleic acids. It is particularly useful for identifying specific genes, analyzing gene expression, or isolating cloned DNA fragments. Here’s a brief overview of the process: 1. **Preparation of a Plaque**: In this context, plaques usually refer to areas of bacterial lysis on a lawn of host bacteria when a bacteriophage (virus that infects bacteria) is present.
