Biotechnology is used in the production of many modern medicines, such as insulin, therapeutic proteins, and vaccines. This process relies on microorganisms like bacteria and yeast to produce these compounds safely and efficiently. These techniques allow the production of high-quality drugs in large quantities while reducing costs compared to traditional methods. Biotechnology also enables the design of personalized medicines tailored to the genetic makeup of each patient, enhancing treatment effectiveness and minimizing side effects. Biotechnology contributes to improving healthcare worldwide, providing innovative solutions for treating chronic and rare diseases, and supporting the rapid development of effective vaccines to combat epidemics.
