Why is CRISPR technology considered a breakthrough in biotechnology?

CRISPR technology is considered a breakthrough in biotechnology primarily because it enables precise genome editing in various organisms. This precision is achieved through the use of a guide RNA that directs the CRISPR-associated endonuclease, such as Cas9, to specific locations in the genome. This capability allows researchers to make targeted changes to DNA—such as inserting, deleting, or modifying genes—quickly and efficiently.

The implications of this technology are vast, ranging from fundamental research in genetics to potential applications in medicine, agriculture, and beyond. For instance, CRISPR can be utilized to correct genetic defects, enhance crop traits, or create animal models for human diseases. This level of precision and versatility is what sets CRISPR apart from older genome-editing methods, which often lacked the same degree of specificity and efficiency.

In contrast, the other options highlight important biotechnological processes but do not capture the unique capabilities of CRISPR. Modifying metabolic pathways, producing monoclonal antibodies, and assisting fermentation processes, while significant contributions to biotechnology, do not reflect the revolutionary genome-editing potential that CRISPR brings to the field. Thus, the focus on precise genome editing makes the second option the correct answer.
