Stanford scientists discover key mechanism in gene expression

Each cell in a person’s body originated from the same single cell. As a result, all the cells possess the same genetic instructions. However, the cells in one tissue are different from another. For example, bone cells have a considerably different morphology as compared to heart cells. This difference is brought about by the expression of genes required for each type of cell. RNA Polymerase II is an enzyme that is largely responsible for the expression of this type of specific gene expression. A team of researchers in Stanford University have observed the DNA being transcribed by this enzyme in real time. This discovery could potentially lead to a leap in genetic engineering as understand the mechanism can play a crucial role in alleviating genetic disorders.
