Not Just A Bag Of Beans

DNA, the genetic blueprint of living organisms, plays an essential role in the continuity of life. Therefore, the structure and function of DNA must be explained to students as simply as possible, using the most appealing methodologies. If DNA, the "language of life"were to be "edited" or changed, then the message it delivers to the cell might also be changed. The result of such changes is variation in the population - an integral part of the evolutionary process. In this laboratory activity, students will (1) determine the types of natural selection, and (2) demonstrate that variation exists in a population, using beans.
