PCR RAP

submitted by: zach.cp
a rap about the Polymerase Chain Reaction that highlights a few things: *the beautiful way in which DNA is copied (using enzymes called Polymerases), *the great insight of Kary Mullis to create a useful tool that could copy DNA in monumental, exponential manner (using primers and heating/cooling cycles). * the human interest side of discovery: the first guy to invent a new technology may just end up with a Nobel Prize, and, should he/she choose, end up riding down Rodeo Drive with movie...

Polyketide Biosynthesis: The Erythromycin Example - Part 2: Impact of Genetics and Molecular Biology on Understanding and Engineering Erythromycin Biosynthesis (22:44)

submitted by: video_collector

In the second part, the contributions of genetics and molecular biology on investigations into erythromycin biosynthesis are summarized. The impact of these fields on biosynthetic engineering is also explained.

Sex and Smell: Molecular Biology of Pheromone Perception: Part 3: Sex-Specificity of Pheromone Responses (30:39)

submitted by: scivee-team

Pheromones have evolved to signal the sex and the dominance status of animals and to promote social and mating rituals. In this lecture, I discuss the how pheromone sensing operates in mammals. I will discuss the molecular biology of the chemosensory receptors that are involved the first steps of pheromone sensing. At a higher level of complexity, I will discuss a distinct olfactory structure called the vomeronasal organ (VNO) and how it contributes to sex-specific behavioral responses.

Plant Viruses and Crops by Roger Beachy, April 2008 - Part 1: Cell and Molecular Biology of Plant Virus Infection: Early Events and Mechanisms of Pathogenesis

submitted by: video_collector

This seminar describes the cell and molecular biology of plant virus infection. The first lecture will discuss how virus replication centers are set up in plants and how viruses use host cell mechanisms to facilitate cell to cell movement and eventual pathogenesis.

A General Definition and Nomenclature for Alternative Splicing Events

submitted by: micha
Understanding the molecular mechanisms responsible for the regulation of the transcriptome present in eukaryotic cells is one of the most challenging tasks in the postgenomic era. In this regard, alternative splicing (AS) is a key phenomenon contributing to the production of different mature transcripts from the same primary RNA sequence. As a plethora of different transcript forms is available in databases, a first step to uncover the biology that drives AS is to identify the different...
