OnScreen Gene Transcription for Android

11 things about OnScreen Gene Transcription

1. The RNA Polymerase enzyme complex, while not shown in the view with the DNA model, so as not to obscure what is happening with bonds and strands, is depicted in the Sequence View below the model, thus making the point that it moves along the DNA, as it initiates and controls the reactions in transcription.

2. Through the use of engaging 3D animations with a virtual double helix model, it makes clear and memorable how a recipe for a protein stored in a gene is made available for use by being copied nucleotide by nucleotide in the construction of a messenger RNA molecule.

3. OnScreen Gene Transcription shows in a detailed, visual, and memorable way how DNA's genetic code gets copied for use in a living cell.

4. The sequence of events in gene transcription unfold in three-dimensional simulations that don't skip over the need for unwinding the DNA after the strands have been separated.

5. Rotate, translate, or zoom the model during the simulated transcription for a better view just by finger slide gestures.

6. Important details about transcription that are often given short shrift or omitted altogether, such as the essential role the enzyme pyrophosphatase plays in the cell, are included.

7. We know of no other simulation of gene transcription on the internet or anywhere else that shows what happens as thoroughly as OnScreen Gene Transcription does.

8. The model is exactly the same as the one found in OnScreen DNA Model, a companion app that teaches the structural details of DNA.

9. Detailed commentary on what the animations demonstrate is available in a popover view.

10. The formation of a hybrid DNA-RNA double helix during RNA construction is correctly shown instead of the two-dimensional ladder structure sometimes depicted.

11. The ball-and-stick model has the advantage of clarity at the expense of atomic detail.
