Explanation:
1. It allows scientists to selectively silence or "turn off" specific genes in a targeted manner. This ability has significant potential in developing gene silencing therapies to treat various genetic disorders and diseases.
2. It has shown promise in cancer research and treatment. By targeting and silencing specific genes involved in cancer progression, RNAi can potentially inhibit tumor growth and development.
3. It is not directly involved in the development of hormone replacement therapies. It is primarily focused on gene silencing and regulating gene expression.
4. It can be utilized in developing genetically modified crops that are resistant to viral pathogens. By introducing specific RNA molecules that target viral genes, plants can be engineered to produce small interfering RNAs (siRNAs) that disrupt the viral replication process and enhance plant resistance against viral infections.
