1.3.2 β pleated sheets
In this unit we explore how proteins are the 'doers' of the cell. They are huge in number and variety and diverse in structure and function, serving both the structural building blocks and the functional machinery of the cell. Just about every process in every cell requires specific proteins. The basic principles of protein structure and function which are reviewed in this unit are crucial to understanding how proteins perform their various roles.

This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nu

Stem Cells Neurological Treatments
This profession video addresses the search for hidden healers within our own genes and stem cells. More and more doctors are looking to the smallest places in the human body for cures that are hidden within genes and stem cells.  The video focuses on a young man who suffered a spinal cord injury that left him paralyzed.  An experimental treatment may hold the key to renewed mobility.  It involves injecting embryotic stem cells into the spine. Another part of the video focuses on a small boy

Reflections on the Current H1N1 Flu
John M. Barry brings unsettling news from the frontlines of H1N1 research: this novel influenza virus is very hard to pin down. In spite of international scientific scrutiny, H1N1 continues to baffle and elude, worrying health officials defending against the pandemic, and challenging some ideas about influenza in general. Says Barry,

Diffusion Across a Sheep Red Blood Cell Membrane
This cell membrane physiology laboratory uses sheep red blood cells to determine: (1) the isotonic and hemolytic molar concentrations of electrolytes and nonelectrolytes, and degree of electrolyte dissociation; (2) the diffusion rate of penetrating molecules of varying size and lipid solubility; and (3) the relationship of molecular size, number of hydroxyl groups, and partition coefficient to diffusion rate. Student research teams then design an experiment using the acquired techniques to deter

Moore's Law Forever?
In 1965, Gordon Moore observed that the number of transistors on a silicon chip doubled every technology generation (12 months at that time, currently 18-24 months). He predicted that this trend would continue for a while. Forty years later, Moore's Law continues to hold. Since the number of transistors in a circuit is a measure of the circuit's computational power, the doubling of transistor counts compounded over a 40 year period has led to an enormous increase in the performance of electronic

MacRetina
MacRetina simulates data from retinal ganglion cells in the eye to the brain. By sampling neural activity while stimulating the retina with small spots of light, students can see the dynamic excitatory and inhibitory responses of these neurons in the simulation, and map the organization of the retinal region that drives the cell's receptive field. MacRetina is modeled accurately on published data and is a realistic simulation of a lab experiment that would otherwise be beyond the reach of the
