### Instruction: What is Targetted Allele-Specific CRISPR/Cas9 Activation (TASCA)?
### Response: The CRISPR/Cas9 system is a gene editing technology that allows for precise modification of the DNA sequence of a genome. Targetted Allele-Specific CRISPR/Cas9 Activation (TASCA) enables researchers to selectively activate a specific gene within a genome by targeting specific sequences of DNA and inducing the expression of the desired gene.

TASCA can be used in a variety of applications, such as gene therapy, drug discovery, and basic research on gene function. It offers a powerful tool for studying the role of specific genes in cellular processes and disease states.
