Introduction to DNA Extractions
Participants in this activity isolate DNA from onion, wheat germ, lima bean bacteria, yeast, and thymus. Visitors to this page will find detailed opening notes to the teacher for putting this activity to work in the classroom, then the subsequent DNA-extraction exercises. Each activity describes the necessary materials, solutions, and protocol--along with helpful tips to the instructor. This is just one of the activities contained at the Access Excellence "Activities Exchange," to which this page links.

What the Heck Is an Enzyme?
Like the other articles in the "What the Heck Is ... ?" series, this page converses in an engaging, friendly way about the science of various biology topics--here, enzymes. The essay links to the "What the Heck?" article contents page and to the main "Bugs in the News!" site of other conversational, yet informative, illustrated articles in its "General Interest" and "More Bug Bytes" series.

Monosaccharide Browser
Visitors to this easy-to-navigate site can view-in color, space-filling Fischer projections of monosaccharides. Users can locate a structure by referring to the alphabetical index or by clicking on carbon atoms to alter chiralty and reveal the name. This site suggests as starting points "D-Glucose," "D-Fructose," and "D-Glyceraldehyde." For example, participants may begin by clicking on "D-Glucose," to bring forth that structure. A click on an asymmetric carbon atom will reverse its chiralty. A variety of panel buttons for each structure--"Reverse All," "Ketose," and "Delete C2"--also enable users to make other changes.

The National Science Foundation MetaCenter Science Highlights Browse
Part of a series of articles describing some of the 10,000 research projects that have used the resources of National Science Foundation supercomputing centers, the reports at this subsite are related to biochemistry and molecular structure and function. The body of projects explored at the main site range from astronomy to zoology--including scientific breakthroughs on vital topics. Each report is illustrated with visuals; many feature animations and audio.

A Periodic Table of the Elements at Los Alamos National Laboratory
A click of the mouse on the element of your choice calls forth a full data page for that element, for example, an element's history, sources, isotopes, common compounds, properties, uses, isotopes, cost, or handling. Users can search for experts in a particular area. The site links back to Los Alamos National Laboratory and to its Chemical Science and Technology Division--both with numerous links and avenues for exploration.

"PDB at a Glance" at The NIH Molecular Modeling Home Page
A hypertext-based classification of the current release of the Brookhaven Protein Databank (PDB), this site provides a set of predefined, biochemically meaningful search contexts accessed by field-specific keywords representing the entire territory of the database. Simply select a category from a convenient contents list, choose from the available PDB files for that structure, and select the information you want to download for RasMol or MAGE viewing. A great way to build your own collection of files.

Protein Science Kinemages
On a tour of this database of interactive "kinemages" (kinetic images), you can rotate structures, activate or de-activate parts of the display, touch points for identification, or animate the change between forms. This site provides access to all kinemages published in Protein Science. Kinemages can be selected through a keyword search or through protein type and filename indexes. The kinemages are created from Brookhaven Protein Data Bank files with the program PREKIN, and the program MAGE is used to view them. (Both programs downloadable for free from this site.)

RasMol Gallery: University of Massachusetts-Amherst
Discover on-line molecular visualization with RasMol--a powerful, free, easy-to-use tool for showing three-dimensional structure of DNA, proteins, and small molecules. At the site are four of RasMol's best: high-resolution images by RasMol creator Roger Sayle. Also featured are RasMol images by Eric Martz: from "movie" scripts on DNA, antibody:antigen, major histocompatibility proteins presenting peptide antigens, SH2 domain with phosphotyrosine, and nonscript images of ATP, tRNA, and lipid bilayers.

RasMol Home Page
This site is devoted to the popularization, distribution, and educational uses of RasMol and other free molecular visualization resources. RasMol is an interactive molecular graphics program that displays proteins, nucleic acids, and small molecules in a variety of colors and representations. View the loaded molecule as wireframe, cylinder (Dreiding) stick bonds, alpha-carbon trace, space-filling (CPK) spheres, and macromolecular ribbons (smooth-shaded solid ribbons or parallel strands), hydrogen bonding, and dot surface. You can rotate, translate, zoom, or z-clip (slab). Atoms may be labeled with arbitrary text strings. Display or color different parts of the molecule independently, or show different representations simultaneously. Space-filling spheres may be shadowed. This site helps you get started and install RasMol or configure RasMol as a viewer to run with a web browser. It features a RasMol Manual, frequently asked questions, enhanced derivatives of RasMol, PDB files, and RasMol accessories.

Scanning Tunneling Microscope Image Gallery-Catalogue
The catalogue provides visitors to this "gallery," an index of scanning tunneling microscope (STM) images displayed as art at this site with atomic-scale images shown in "exhibition rooms," along with a "library" of references relevant to each image.

Display or color different parts of the molecule independently, or show different representations simultaneously. Space-filling spheres may be shadowed. This site helps you get started and install RasMol or configure RasMol as a viewer to run with a web browser. It features a RasMol Manual, frequently asked questions, enhanced derivatives of RasMol, PDB files, and RasMol accessories.

Scanning Tunneling Microscope Image Gallery-Catalogue
The catalogue provides visitors to this "gallery," an index of scanning tunneling microscope (STM) images displayed as art at this site with atomic-scale images shown in "exhibition rooms," along with a "library" of references relevant to each image.

WebElements: Links to Biological Information
Visit this on-line periodic table for a closer look at the elements. At this link, a click of the mouse on a desired element calls forth biological data for that element, including biological role, hazards and risks, toxicity, and levels in humans. At the larger site, you may consider the elements from a general, chemical, physical, nuclear, electronic, geological, or crystallographic perspective. Take a look at reduction potentials, isotope abundances, electronic configurations, ionization enthalpies, and more.; "PDB at a Glance" at The NIH Molecular Modeling Home Page; A hypertext-based classification of the current release of the Brookhaven Protein Databank (PDB), this site provides a set of predefined, biochemically meaningful search contexts accessed by field-specific keywords representing the entire territory of the database. Simply select a category from a convenient contents list, choose from the available PDB files for that structure, and select the information you want to download for RasMol or MAGE viewing. A great way to build your own collection of files.

Protein Science Kinemages
On a tour of this database of interactive "kinemages" (kinetic images), you can rotate structures, activate or de-activate parts of the display, touch points for identification, or animate the change between forms. This site provides access to all kinemages published in Protein Science. Kinemages can be selected through a keyword search or through protein type and filename indexes. The kinemages are created from Brookhaven Protein Data Bank files with the program PREKIN, and the program MAGE is used to view them. (Both programs downloadable for free from this site.)

RasMol Gallery: University of Massachusetts-Amherst
Discover on-line molecular visualization with RasMol--a powerful, free, easy-to-use tool for showing three-dimensional structure of DNA, proteins, and small molecules. At the site are four of RasMol's best: high-resolution images by RasMol creator Roger Sayle. Also featured are RasMol images by Eric Martz: from "movie" scripts on DNA, antibody:antigen, major histocompatibility proteins presenting peptide antigens, SH2 domain with phosphotyrosine, and nonscript images of ATP, tRNA, and lipid bilayers.

RasMol Home Page
This site is devoted to the popularization, distribution, and educational uses of RasMol and other free molecular visualization resources. RasMol is an interactive molecular graphics program that displays proteins, nucleic acids, and small molecules in a variety of colors and representations. View the loaded molecule as wireframe, cylinder (Dreiding) stick bonds, alpha-carbon trace, space-filling (CPK) spheres, and macromolecular ribbons (smooth-shaded solid ribbons or parallel strands), hydrogen bonding, and dot surface.
