A gene bank is a place where special cells are stored that contain the genetic information of plants, animals, or even people. It is kind of like a library, but instead of books, the “books” are tiny microscopic pieces of genetic material. We keep genetic material in gene banks because it can be used to help us learn more about living things, or even to create new kinds of plants or animals. Genetic material can be kept in gene banks for a very long time, so scientists can use it to study things now and in the future.
