Summary Introduction

To describe: The three stages of CRISPR/Cas response to viral infection.

Introduction: Microbial cells have various systems to fight against viral infections. The examples of such defensive systems include restriction-modification (innate system) and CRISPR/Cas system (adaptive immune system). The genetic elements of the invading virus are used as a memory by the CRISPR/Cas system to prepare for a possible future attack.

Summary Introduction

To explain: The role of quorum sensing in the CRISPR/Cas system.

Introduction: Quorum sensing is a mechanism for gene regulation in bacteria. This mechanism is dependent upon the population density and the signal molecules. This mechanism was first observed by a microbiologist Alexander Tomasz in the mid-1960s.
