Add to EJ Playlist  NDSU VCell Production's animation "Mitosis". For more information please see http://vcell.nd su.edu/animatio ns. Mitosis is the process by which the chromosomes in the nucleus of a cell are divided into into two new nuclei. This animation illustrates how the stages of mitosis progress and eventually lead to the formation of two new cells.

Add to EJ Playlist  NDSU Virtual Cell Animations Project animation "Regulated Transcription". For more information please see http://vcell.nd su.edu/animatio ns. Gene expression is controlled in many different ways. When proteins from outside a cell signal for a specific gene to be transcribed, it is known as regulated transcription. This animation illustrates how a protein like insulin can trigger a regulated transcription event, in addition to setting off the signal pathway illustrated in our Insulin Signaling video.

Add to EJ Playlist  NDSU Virtual Cell Animations Project animation 'Insulin Signaling'. For more information please see http://vcell.nd su.edu/animatio ns. When high levels of glucose enter the blood stream, insulin is released by beta cells in the pancreas. Insulin then initiates a number of signal pathways in specific muscle and fat cells. This takes a look at the signal pathway responsible for allowing those cells to rapidly increase their ability to uptake glucose from the blood stream.

Add to EJ Playlist  NDSU Virtual Cell Animations Project animation 'Protein Recycling'. For more information please see http://vcell.nd su.edu/animatio ns. Certain intercellular proteins are needed to respond to specific extracellular signals. This movie covers how such proteins can be stored, recycled and kept available during the periods of time in between the arrival of such extracellular signals.

Add to EJ Playlist  NDSU Virtual Cell Animations Project animation 'Regulated Secretion'. For more information please see http://vcell.nd su.edu/animatio ns. Proteins can be secreted, or transferred out of a cell, by multiple pathways. Regulated secretion is one of these processes. In regulated secretion proteins are secreted from a cell in large amounts when a specific signal is detected by the cell. The example used in this animation is the release of insulin after a glucose signal enters a pancreatic beta cell.

Add to EJ Playlist  NDSU Virtual Cell Animations Project animation 'Constitutive Secretion'. For more information please see http://vcell.nd su.edu/animatio ns Proteins can be secreted, or transferred out of a cell, by multiple pathways. Constitutive secretion is one of these processes. In constitutive secretion proteins are secreted from a cell continuously, regardless of external factors or signals. This pathway is also used by all eukaryotic cells to maintain the cell's plasma membrane.

Add to EJ Playlist  NDSU Virtual Cell Animations Project animation 'Protein Modification (Golgi)'. For more information please see http://vcell.nd su.edu/animatio ns Protein modification is the process by which some proteins from the rough ER are altered within the Golgi apparatus in order to be targeted to their final destinations.

Add to EJ Playlist  NDSU Virtual Cell Animations Project animation 'Lac Operon'. For more information please see http://vcell.nd su.edu/animatio ns The Lac Operon is an example of an inducible system of gene expression. Its default state is to be inactive. Only when the right catalyst is added to the system, in this case the sugar lactose, is the process activated, allowing the genes in question to be expressed.

Add to EJ Playlist  NDSU Virtual Cell Animations project animation "Translation". For more information, see http://vcell.nd su.nodak.edu/an imations Translation is a key process in biological lifeforms. It is this set of events that transforms the code contained in DNA and later mRNA into the proteins necessary for cellular life.

Add to EJ Playlist  NDSU Virtual Cell Animations Project animation 'mRNA Splicing'. For more information please see http://vcell.nd su.edu/animatio ns Before being used in translation, mRNA must be spliced. During splicing, introns are removed and the translatable exons that remain are spliced into a single strand of mRNA.

For more information please see http://vcell.nd su.edu/animatio ns Transcription is a vital process in biological lifeforms. It is through this process that the biological roadmap encoded in a strand of DNA is used to produce a complementary RNA copy. The RNA can then go on to help produce the proteins and enzymes that power living organisms.
