Cell Architecture WWW

Cell Architecture is presented by Karl Johnson, Haverford College, Pennsylvania

This page last updated 11/21/2014

Each chapter of this e-text is a compedium of information, images and other open source materials gathered to help you explore the eukaryotic cell and is followed by an interactive discussion of a recent paper that is influencing the way we look at the cell from structure/function perspectives.

Cell Architecture debuted at Haverford College in 1993-1994 and first ventured on the World Wide Web in 1994-1995 (using the "first" web browser, NCSA Mosaic 0.53b). It subsequently has grown through several major rebuilds and is continuously edited, modified and updated as ideas grow and change (it is, after all, biological!). While I have tried to make this text a stand-alone resource freely available to all, there is no substitute for coming to Haverford and joining our class. Visitors, virtual or real, are always welcomed!

Sources from which images are cached are available below the accompanying commentary text, and almost every image and video was downloaded from other open-access, open-source sites; our effort is largely collecting and making sense of it all. Our sincere thanks to everyone who makes their work available on the Internet for teaching purposes, and it is in reciprocity that we hope you enjoy this site. We do not claim copyright for any of this material; we have simply cached and organized freely accessible material providing a link to its source (based on the model of a web search engine). This approach was necessary to provide a stable resource in the fluid environment of the Web. Known issues: videos shown in-class do not play in the lecture notes (we are working on this!).

Literature links: All article links point directly to the corresponding journal web site, and so anyone visiting this page will be able to access articles to which their institution has arranged library access. This should be seamless and transparent for most users, including Haverford, Bryn Mawr and Swarthmore students on their campus networks. For Haverford students who travel off-campus, articles access is possible by using our campusVPN service or ezproxy.haverford.edu.

Finally, for students in the class, biweekly question sets will form the basis for your evaluation in this course. The question sets will be distributed to members of the class a week before the due date by link to the table below. Each will consist of several open exploration questions and students are expected to use the resources of the web, particularly the scientific literature, in forming their responses. Completed question sets should be submitted electronically as .doc or .docx files as e-mail attachments to Karl Johnson . As always, back-up work in progress and retain a copy of your submission file until your work is graded and returned. Early submissions are welcomed; late work will be accepted but will be marked down a grade for each day (24 hour period) it is late based on submission times recorded by the e-mail server. Each student's grade in the course will be based upon these question sets (@20%) and a class attendance/participation mark (40%).

Functionality/Environment (Chapters IX-XII)

Saturday, 12/6/2014
Saturday, 12/13/2014

In December, 2014, Philadelphia is hosting the annual American Society for Cell Biology Meeting in the downtown convention center. There is a special program for undergraduate students on Saturday, Dec. 6th, that involves a Graduate School Fair, several presentations, and a poster session. Registration is free but must be submitted in advance using this form. This is a great opportunity to learn about graduate programs and experience the excitement of a large, professional meeting literally at our doorstep. Please consider attending; to encourage participation, Cell Architecture students who do so may submit a two page synopsis of their experience at the meeting in place of their third question set.

I hope you enjoy Cell Architecture! Please feel free to contact me with suggestions and comments!
