Lighting Up: Analysis Of Yeast RAS Genes Using A Chemiluminescent Southern Blot Procedure
Genomic and plasmid-encoded RAS2 genes from Baker's and brewing yeast strains will be analyzed using a shortened Southern blot procedure employing chemiluminescence. Unique parts of this procedure are the gravity-driven "upside down" transfer and a rotisserie-like hybridization oven, which greatly facilitate shortening the transfer time to 45 minutes and the hybridization step to 60 minutes. Chemiluminescence obviates problems associated with radioisotopes without sacrificing sensitivity: the pl

The tone of the neck can be assessed by passively rotating the head towards the shoulder. The chin should be able to rotate to the shoulder but not beyond the shoulder. If the chin goes beyond the shoulder then there is hypotonia of the neck muscles, which is associated with poor head control. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an emphasis on important neurodevelopmental milestones.

Dermatoglyphics is the study of epidermal ridges on the hands and feet. Ridge patterns and counts develop prenatally, are inherited, and show quantitative variation. This exercise introduces the preparation and interpretation of finger and palm prints for quantitative analysis. The techniques are simple, inexpensive, and can be adapted as an exercise on genetics for beginning or advanced students. Palm prints from individuals with Down Syndrome serve as a population sample to statistically test
Using a well-known formula, Mr. Khan focuses on a framework for thinking about how many detectable civilizations are out there. He uses computer software for instruction. (08:53) Why do we even care about the Drake Equation? Thinking about the fraction of a planet's life when a civilization might be detectable.
Students will design and build a prototype of an artificial limb using a simple syringe system as an introduction to bioengineering. Students will determine which substance water (liquid) or air (gas) will make the appendage more efficient.
This read-aloud is The Perfect Purple Feather written by Hanoch Piven. Feeling a poke from within his pillow during the night, Jacob maneuvers a fluffy purple feather to the surface. Beginning with a bluebird in a nearby tree, various animals explain how they would put it to good use-as a wing, a pen, a tail, etc. When a tick tickles an elephant's nose with it, the elephant sneezes, causing the feather to fly through the sky, suggesting the possibility that it may land in the reader's bedro
This read-aloud is Blossom and Boo Stay Up Late written by Dawn Apperly. It is a cute story about two animal friends who want to see what the forest is like at night. There is a play button to get story started and a pause button on each page. Each word is highlighted as the speaker reads. The speaker changes voices with each character. This is a wonderful resource for building a literacy rich environment in the classroom. It would be beneficial for struggling readers and/or special education st
This chapter describes a multi-week project taught in an upper level cell and molecular biology laboratory. Isolation of sufficient quantities of rare proteins from biological tissues can be difficult. These native proteins are often required for raising antibodies, and for studying enzymatic or regulatory function. Expression vectors are used to obtain large quantities of proteins. The cDNA encoding a protein is cloned into an expression vector. The fusion protein is over-expressed in E. coli,
This patient education program reviews urinary tract anatomy and symptoms to explain what an intravenous pyelogram (IVP) involves, including the benefits and risks of this procedure. This is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.
