... storage, where massive amounts of data are collected and stored simply because we can do so and not because of some designed experiment, questions are often generated after the data have been collected ... called genes. The genome is the complete DNA for an organism, and it contains the genetic code needed to create a unique life. The process of gene activation is called gene expression...
