Lesson on Wernicke’s Encephalopathy: Causes, Signs/Symptoms, Treatment. Wernicke’s encephalopathy is an acute, reversible encephalopathy caused by a vitamin deficiency that we discussed in this lesson. A subset of patients are...

Irreversible Inhibition: A Mechanistic Approach

Lesson on Korsakoff's Syndrome (part of Wernicke-Korsakoff syndrome), pathophysiology and brain area damages, causes, symptoms and possible treatments. Korsakoff's syndrome is a chronic and often irreversible encephalopathy is often...

This nugget describes historical aspect of discovery of nucleic acid, basic structure of polynucleotide chain, Watson model of DNA and types of DNA.

Lesson on the purine and pyrimidine degradation pathway, the critical enzymes involved in the pathway (xanthine oxidase) and what the body does with the products of pyrimidine catabolism (beta alanine and beta aminoisobutyrate) and...

We've learned a lot about DNA, but sometimes the representations of DNA that we use to talk about it are not especially accurate. Everyone knows the popular image with the ladder rungs, but let's really get in there and visualize DNA in...

Genetic Expression Set: 3. This clip examines the chemical structure of DNA and RNA and explains how the genetic code is written and expressed.

Melanin Physiology: Melanin Absoprtion of UV Light and Internal Conversion to Heat

We've been hearing about DNA since the third grade, and we all know that it's a double helix with little ladder rungs. But now we are ready to understand this molecule on a more fundamental level, which will enable to us to understand...
