WebThe study of gene induction by IR is important to the understanding of how cells and organisms respond to radiation exposure. IR activates the transcription of a number of genes, implying the existence of radiation-responsive elements residing upstream of IR-induced genes.

WebX-inactivation is a random process that happens separately in individual cells during embryonic development. One cell might shut down the paternal X, while its next-door neighbor might shut down the maternal X instead. All the cells descended from each of these original cells will maintain the same pattern of X-inactivation. WebA genetic mutation is a change in a sequence of your DNA. Your DNA sequence gives your cells the information they need to perform their functions. If part of your DNA sequence is in the wrong place, isn’t complete or is damaged, you might experience symptoms of a genetic condition. Cleveland Clinic is a non-profit academic medical center.
