Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced Short...

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea. The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

The video outlines a process for creating genetically modified CAR T cells through the CRISPR-Cas9 System. Infecting T cells with CRISPR and CAR lentiviruses results in modifications to the target gene and the synthesis of a chimeric antigen receptor or CAR, ultimately leading to the formation of genetically modified CAR T cells.

CRISPR/Cas systems mediate adaptive immunity in Bacteria and Archaea. Many Cas proteins are proposed to act as endoribonucleases acting on crRNA precursors of varying length. Here we illustrate three different approaches to generate pre-crRNA substrates for the biochemical analysis of Cas endonuclease activity.

FAQs
The guide RNA determines where the CRISPR-associated nuclease acts by pairing with a complementary DNA sequence. Once positioned, the nuclease creates a double-strand break at that genomic location. This break is the key entry point for integration because it engages the cell’s own repair machinery, allowing a supplied genetic sequence to become part of the genome.
The donor sequence provides the genetic material intended for insertion, while the repair route determines how that material is incorporated. In homology-directed repair, matching regions guide use of the donor sequence. Other integration mechanisms can also be used, but they are not described as relying on the same homology-based process. Cellular repair activity therefore shapes the final modification.
Genome-level insertion can maintain a genetic change in the modified cell, which is important when experiments require sustained reporter expression or a lasting replacement rather than a temporary intervention. In neural models, that persistence supports examination of gene function over the course of a study and helps connect a defined genetic alteration with neuronal or disease-related outcomes.
Reporter insertion and gene replacement use the same general editing logic but answer different biological questions. A reporter can provide a way to track gene expression, whereas replacement is intended to supply a selected genetic sequence in place of a target-related sequence. Functional studies then examine how the resulting modification affects neural models, linking the engineered change to gene roles.
A conceptual workflow begins by selecting the genomic DNA sequence to be addressed, designing a complementary guide RNA, and pairing the guide with a Cas nuclease. A donor sequence is supplied when insertion or replacement is required. After the nuclease creates the break, cellular repair incorporates the donor through homology-directed repair or another integration mechanism, producing a stable modification.
In neuroscience, this strategy is useful when researchers need a stable genetic change in neurons or other neural models. They can install reporters to support expression studies, perform gene replacement to test gene function, or create modified systems for investigating brain development and neurological disease. These applications turn a targeted genomic change into a platform for functional analysis.
The resulting models can provide more than evidence that DNA was modified. Stable reporter expression can support observation of gene expression, while gene replacement and related edits enable functional studies of gene roles. In neural research, these outcomes can clarify contributions to brain development or disease and support the development of cell-based models and potential therapeutic strategies.
