Bookmarking
Bookmarking (Medical)
Bookmarking (pronunciation: /ˈbʊkˌmɑːrkɪŋ/) is a term used in the field of genetics and epigenetics to describe the process by which certain genes are marked for activation or inactivation during cell division. This process is crucial for maintaining the identity and function of different cell types in the body.
Etymology
The term 'bookmarking' is derived from the analogy of using a bookmark to mark a specific page in a book for easy reference in the future. In the context of genetics, bookmarking refers to the marking of specific genes for future reference during the process of cell division.
