6.1 Introduction
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
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
Boudreaux on Monetary Misunderstandings
Don Boudreaux of George Mason University talks with EconTalk host Russ Roberts on some of the common misunderstandings people have about prices, money, inflation and deflation. They discuss what is harmful about inflation and deflation, the importance of expectations and the implications for interest rates and financial institutions.
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
7.342 Reading the Blueprint of Life: Transcription, Stem Cells and Differentiation (MIT)
In this course, we will address how transcriptional regulators both prohibit and drive differentiation during the course of development. How does a stem cell know when to remain a stem cell and when to become a specific cell type? Are there global differences in the way the genome is read in multipotent and terminally differentiated cells? We will explore how stem cell pluripotency is preserved, how master regulators of cell-fate decisions execute developmental programs, and how chromatin regula
RVC 05 - Equine Stem Cells
Stem cells have been making big waves in science recently. Listen to this episode of the RVC Podcast to find out how Roger Smith, Professor of Equine Surgery at the RVC, is planning to use innovative stem cell research in order to improve the treatment of tendon disease in horses.
