What advantage does CRISPR technology provide in gene editing?

• A. It allows for random gene mutations
• B. It facilitates precise alterations of DNA sequences
• C. It reduces the need for experimental models
• D. It guarantees successful gene therapy

Answer: (B)

CRISPR technology stands out in gene editing primarily because it facilitates precise alterations of DNA sequences. This system uses a guide RNA to target specific stretches of genetic code in the genome, allowing scientists to make precise cuts at exact locations. The targeted nature of this editing enables researchers to add, delete, or modify genetic material in a very controlled manner, which is crucial for correcting genetic disorders, enhancing crop traits, or studying gene functions. While the other options do present aspects related to genetic research and editing, they do not capture the primary advantage of CRISPR. The technology does not create random mutations; instead, it is defined by its specificity. Moreover, although CRISPR may reduce the need for experimental models in some cases, it does not eliminate them entirely, as many experiments still require validation in living organisms. Lastly, while CRISPR holds great promise for gene therapy, it does not guarantee success in every application, as outcomes depend on factors such as delivery efficiency and the context of the genetic changes being made.
