The Power of RNA Interference in Gene Regulation and Therapeutic Applications

The video explores RNA interference (RNAi), a process where RNA silences genes by targeting mRNA. It details the mechanisms involving dsRNA, dicer, and RISC, and discusses RNAi's applications in medicine and agriculture. The potential of RNAi in biotechnology is highlighted, emphasizing its role in gene therapy and crop protection.
