Which technology is commonly associated with gene editing?

• A. Polymerase chain reaction
• B. DNA sequencing
• C. Genetic mapping
• D. CRISPR

Answer: (D)

The technology most commonly associated with gene editing is CRISPR. CRISPR, which stands for Clustered Regularly Interspaced Short Palindromic Repeats, is a revolutionary tool that allows researchers to modify an organism’s DNA with high precision, efficiency, and flexibility. This ability to target specific genes and make alterations, such as inserting, deleting, or modifying sequences, has transformed the field of genetics with applications ranging from agriculture to medicine. CRISPR operates through a guide RNA that directs the Cas9 enzyme to the specific location in the DNA where the edit is desired. Once there, Cas9 acts like a pair of molecular scissors, cutting the DNA at that location so that the cell can then repair the break, often incorporating the desired genetic changes in the process. This method is not only cost-effective but also simpler compared to previous gene-editing techniques. In contrast, the other technologies mentioned serve different purposes within the realm of biotechnology. Polymerase chain reaction is primarily used for amplifying DNA, DNA sequencing pertains to determining the order of nucleotides in a DNA molecule, and genetic mapping involves identifying the locations of genes on chromosomes but doesn’t involve the direct modification of gene sequences like CRISPR does.
