Of particular interest were a set of genes that were related to gene transcription, translation, and regulation. These are important because the genetic material in an individual needs to be copied and transcribed into every new cell as the body grows and repairs itself. You can conceptualize this as requiring an internal Xerox machine for genetic material. If the glass plate on the Xerox machine becomes dirty over time, it will affect the accuracy of copies—and when it comes to genetic material, will ultimately affect how well the new cells can function.
