DNA and Genetic DisordersThis interactive program takes students on a tour of cells and DNA. It illustrates how DNA is transcribed into RNA and the RNA is translated into protein, and how proteins fold in order to have a function. It then illustrates how a mutation in the DNA can lead to a non-functional protein. (Run Time = ~4 minutes, 4.8mb) Download Flash Movie (PC) Download Flash Movie (Mac) |

DNA to RNA to Protein - What does it all mean?This narrated movie illustrates the process of gene expression, the transcription of DNA into RNA and the translation of RNA into proteins, as well as protein folding. It also illustrates how expressing different genes in different cells can lead to cells with different characteristics and functions.

Electrophoresis - Separating by LengthThis movie illustrates how individual strands of DNA move through a gel during the process of electrophoresis, and how this can result in the separation of DNA fragments on the basis of length. The gel polymers are shown in green, and the DNA fragments are shown in blue. (Run Time = ~15 sec, 25kb) Download Flash Movie (PC) Download Flash Movie (Mac) |

Electrophoresis - What's in a Band?After seeing how individual strands of DNA move through a gel, this movie illustrates how many of those fragments can appear as a band of DNA on a gel. The well of a gel is shown in light blue. DNA fragments start in the well. When an electrical current (illustrated by the positive and negative poles at the top and bottom of the well) is applied, the DNA moves toward the positive pole. Groups of similarly sized fragments travel together through the gel, and are observed as a "band", which represents many similarly sized fragments.

Protein ElectrophoresisThis narrated, interactive program illustrates how proteins can be separated on basis of length. Since proteins exists as folded structures, this program also illustrates how the structure of the protein is unfolded by STS prior to performing electrophoresis.

AIDS, HIV and tRNAAdapted from a research paper published in 2001, written by Matthew Renda and others, this interactive paper describes and experiment that tests whether an altered tRNA can be used to stop Human Immunodeficiency Virus (HIV) from converting its single-stranded RNA into double-stranded DNA. This conversion is a necessary step for HIV to infect human cells.
