Overview
Viral vectors are biological agents, usually viruses, that are used to deliver genetic material into target cells. They are widely used in biotechnology and for medical applications, such as gene therapy and vaccines. Viral vectors have the ability to penetrate and pass genetic material into cells, allowing for the transfer and expression of new genetic information. This can be used to modify the cells, replace defective genes, and to prevent or treat diseases. Viral vectors are also used for research purposes to study gene functions and gene regulation, as well as for biotechnological applications, such as producing proteins and vaccines. By using viral vectors, researchers can gain insight into how cells respond to genetic changes, and how a gene can be used to treat diseases.
