As you read this many of the cells in your body are in a gradual process of division which results in the production of two daughter cells. In this process, known as mitosis, the cell duplicates its contents, including its DNA, before dividing. But the hardware is only part of a cell. Like a computer the cell contains programming information. For instance, tiny chemical signals—methyl groups—may be added to certain proteins or DNA sequences. You can read here about one way that this programming information is passed on to later generations. New research is now elucidating a different mechanism for preserving the cell’s programming information. Read moreMitotic Bookmarking Facilitates Transmission of Genetic Programming
