Can genes turn on and off
WebThe biologists in Freiburg together with researchers from the Max-Planck-Institute for Developmental Biology in Tuebingen have now described how microRNAs not only indirectly turn off genes by obstructing mRNAs, but can also turn off genes directly. In the process the genes are silenced chemically by adding methyl groups. Webexplain how gene regulation leads to cells with many different properties. Cells with the same genetic info develop into different types of cells through gene regulation. Gene regulation is the mechanisms that turn on certain genes while other genes remain turned off. Regulating gene activity allows for specialization of cells within the body.
