3 Apps in This Bundle

NOTE: You can buy one of the bundled apps to verify the quality, then pay the difference to complete the bundle. With vivid and memorable interactive 3D simulations, these three apps, taken together, provide a thorough grounding in the basic structure of DNA, how genes are copied for use in the cell, and how DNA makes a copy of itself during cell division. They were all selected by reviewers of the National Science Teachers Association for inclusion in the NSTA Recommends resource guide for Grades 6-College. Background material, keys to the color coding of DNA components, and commentary about steps in the DNA processes are built into the apps. The animated simulations may be paused at any time. The DNA model is scientifically correct in its geometry, including relative size of the spacing between nucleotides and the helical radius, helix handedness, angle offsets between paired bases, and bases per helical turn. The role of enzymes in the processes is emphasized. There is no better or more enjoyable way to "get up to speed" on how DNA works, and no previous knowledge is assumed. Apps have been tested with iOS 8.
