Organisms look similr because their body designs are similar. If the body designs are to be similar the blueprints or copies of these designs should be similar. Thus reproduction at its most basic level involves making copies of body design. This can be done only if a copy of DNA is made. The nucleus contains chromosomes which contains info. for inheritance offeatures from parents to next generation in the form of DNA molecules.
