Retrogenetics is a branch of genetics that focuses on understanding and manipulating the genetic information of organisms by studying retrotransposons, which are sequences of DNA that can change their position within the genome. This field explores how these elements influence gene expression, evolution, and genetic diversity. By employing techniques like reverse genetics, researchers can investigate the functions of specific genes and their roles in various biological processes. Ultimately, retrogenetics provides insights into genetic mechanisms and potential applications in biotechnology and medicine.
