Gene transfer is a research area focused on the process of transferring genetic material (such as DNA or RNA) from one organism to another. This can involve transferring genes between different species, cells, or organisms in order to introduce specific traits or characteristics, or to study gene function and regulation. Gene transfer techniques can be used in various fields of research, such as genetic engineering, biotechnology, and gene therapy. This area of research is important for understanding the mechanisms of genetic inheritance and evolution, as well as for developing new technologies and treatments for genetic diseases.
