Definition of gene editing

Gene editing involves the precise alteration of the DNA within a living organism’s genome. This process allows scientists to modify specific genes responsible for various traits or genetic disorders. It’s essentially the genetic surgery of the modern age, enabling targeted changes to the genetic code.

Explanation of how gene editing works

Gene editing primarily operates through introducing specific changes to the DNA sequence of an organism. Scientists utilize specialized tools like CRISPR/Cas9 to target and edit specific regions of the genetic code. By making strategic modifications, they can correct mutations, introduce desired traits, or study gene functions in greater detail.

Steps in gene editing process:

• Identification of Target Gene: Scientists pinpoint the gene they want to modify.
• Designing Gene Editing Tool: Tools like CRISPR/Cas9 are engineered to target the selected gene.
• Delivery: The editing tool is delivered into the cells where the gene is located.
• Gene Modification: The tool makes precise cuts in the DNA, allowing for editing.
• Cell Repair: The cell’s repair mechanisms fix the DNA based on the introduced edits.

Different methods of gene editing (e.g. CRISPR/Cas9)

One of the most popular methods of gene editing is CRISPR/Cas9, known for its accuracy and efficiency in modifying genetic material. This technique involves using a guide RNA to direct the Cas9 enzyme to the target DNA sequence, where it creates a double-strand break. This break triggers the cell’s repair mechanisms, enabling precise alterations to the gene sequence.

Other gene editing methods:

• TALENs (Transcription Activator-Like Effector Nucleases): Another genome-editing tool that operates similarly to CRISPR/Cas9 but utilizes TALE proteins for DNA binding.
• ZFNs (Zinc-Finger Nucleases): These enzymes can be custom-designed to bind and cut specific DNA sequences, facilitating gene modifications.
