Scientists find missing factor in gene activation

Scientists have unraveled a mystery on how genes are activated. Human genes are blocked by structures known as nucleosomes, components that package DNA inside cells. How do these roadblocks clear out to allow genes to be turned on? Scientists have identified a key factor that unravels nucleosomes and clears the way for gene activation. They say the finding is useful in understanding diseases such as cancer, which can be caused by improper gene activity. (Mehr in: Cancer News — ScienceDaily)
