Topic: The Science Behind Human Gene Editing (Questions 14-26)
Passage Text: The Science Behind Human Gene Editing
Gene editing refers to the deliberate modification of an organism’s DNA to alter specific traits. The most revolutionary development in this field is **CRISPR-Cas9**, a tool that allows scientists to “cut and paste” genetic material with **unprecedented precision**. The potential benefits are enormous: curing genetic diseases, improving agricultural resilience, and even preventing hereditary disorders before birth.
The CRISPR process works by using a **guide RNA** molecule to target a specific DNA sequence. The **Cas9 enzyme** then makes a precise cut at that location, after which cellular mechanisms repair the DNA — sometimes incorporating new genetic information in the process. This simplicity has made CRISPR the **most widely adopted** gene-editing technique in laboratories worldwide.
Yet, with great power comes ethical complexity. Editing human embryos raises moral questions about “**designer babies**” and the manipulation of human evolution. Many bioethicists argue that germline editing — changes passed down to **future generations** — could have unforeseen effects on human diversity and natural selection. Others, however, emphasize its potential to eliminate devastating diseases such as cystic fibrosis or **muscular dystrophy**.
Internationally, regulations vary. Some countries, like the **UK**, permit limited embryo research under strict conditions, while others completely ban human germline modification. The scientific community continues to **debate** how far human intervention should go and who should decide the boundaries of such transformative technology.
