A positive use of viruses is delivering genetic material.
A positive use of viruses is delivering genetic material. Viruses can be engineered to carry specific genes or DNA sequences and target specific cells for delivery. This is commonly used in gene therapy, where viruses are utilized as carriers to deliver therapeutic genes into cells to treat genetic disorders or other diseases.
To get this answer, you can consider the applications of viruses in different fields of research and technology. One such application is gene therapy, where viruses are used to deliver therapeutic genes into cells. By understanding the concept of gene therapy and the role of viruses in this process, you can identify delivering genetic material as a positive use of viruses.
