Change and rates of change can be quantified and modeled over very short or very long periods of time. For engineering, they should ask questions to define the problem to be solved and to elicit ideas that lead to the constraints and specifications for its solution. The technique utilizes the fact that DNA is negatively charged along its backbone.
