DESCRIPTION
Vector illustration of DNA strand with chromosones fading in dark background. DNA contains the genetic instructions for development and functioning of all known living organisms and some viruses. DNA can be used to detect diseases, or catch (identify) criminals. The DNA strand is often compared to a set of blueprints, a recipe, or a code, since it contains the information needed to construct other components of cells, such as proteins and RNA molecules.The DNA segments that carry this genetic information are called genes.
