What is the term for a piece of DNA intended for insertion into the nucleus of a cell?

A transgene refers to a piece of DNA that has been deliberately inserted into the genome of an organism through genetic engineering techniques. This DNA can be derived from the same species or a different species, enabling scientists to introduce new traits or functions into the target organism. In the context of laboratory animal studies, transgenes are often used to create models for human diseases, study gene function, or assess gene therapy approaches.

Understanding transgenes is essential in the field of genetic research and biotechnology because they allow for the study of complex biological processes in living organisms. The introduction of transgenes is facilitated by vectors, which are carriers used to deliver the transgene into the target cells effectively. While plasmids and vectors play crucial roles in the transgenic process, the term specifically describing the inserted DNA itself is transgene.
