If you are thinking of taking this (or any) course with me, you should read the Course FAQ!

Here are some general sites for useful animations. (A picture is worth a thousand words, a movie worth a thousand pictures ....)

General Sites:
HHMI BioInteractive: http://www.hhmi.org/biointeractive/
McGraw Hill offers animations other than the ones for our text. Here are some:

Life inside the cell (as well as a few other videos): http://multimedia.mcb.harvard.edu/media.html

This site offers fantastic animations showing several complex cellular processes in an easy-to-understand visual format:


<Interactive> Mathematics Skills

In medicine and science, math is as critical to success as language. In particular, the ability to change from one set of units to another is required. These exercises can help you brush up on basic skills, if you need to do so.

In my opinion, one of the best sites on the net is this one: The Khan Academy.

Cellular Replication

DNA Replication:
1) http://highered.mcgraw-hill.com/sites/dl/free/0072835125/126997/animation17.html

2) An overview of DNA Replication:

3) https://www.youtube.com/watch?v=-mtLXpgjHL0&list=PL86FB28667714C01D

4) These are probably the most realistic, and best, animation of DNA replication available:
    Note: all of the HHMI videos on DNA are here: http://www.hhmi.org/biointeractive/dna/animations.html

5) This is a good introduction to DNA replication, but it is necessary to click the "play" button repeatedly. A printable text-only version is available for off-line study.

6) A nice, short overview of DNA synthesis:  http://www.freesciencelectures.com/video/dna-replication-process/

7) From Mcgraw-Hill: How errors are avoided during DNA synthesis: http://highered.mcgraw-hill.com/classware/ala.do?isbn=0072956208&alaid=ala_996023&showSelfStudyTree=true

8) http://www.hartnell.edu/tutorials/biology/dnareplication.html

1) https://www.youtube.com/watch?v=AJNoTmWsE0s&list=PL86FB28667714C01D

Mitosis, Cytokinesis, and Meiosis:
1) A cute (for lack of a better word) game to teach how the cell cycle is controlled is found here:

2) An excellent animation explaining checkpoints can be found here: http://outreach.mcb.harvard.edu/animations/checkpoints.swf

3) Two other animations on meiosis worth watching are found on this page:

Gene Expression

1) http://www.genomebc.ca/education/teachers/classroom-activities/gene-expression/
2) Several animations prepared by McGraw-Hill for use with "Brooker Genetics" site are useful:
3) Sumanas, Inc., hosts an excellent animation discussing the structure of DNA (which is useful background information in studying gene expression):
4) Sumanas, Inc., also have an excellent animation on translation:
5) Several animations prepared by McGraw-Hill for use with "Raven's Biology, 7th edition" are useful:


There are many useful activities and animations at these sites:

The Genetic Science Learning Center at the University of Utah is a fantastic resource for biotechnology and genetics in general, but is particularly useful if you want to learn more about the answers to these questions:
  • What types of stem cells exist? What are the important differences between them?
  • What is the goal of stem cell research?
  • How are stem cells created?
  • How is an entire animal cloned?
  • What are some common misconceptions about cloning?

If you don't have time to view all of the Molecular Biology and Biotechnology links, be sure to at least visit these:
http://www.dnai.org/ ... ... Select the "Human Identification" button at the bottom, and then "murder" at the top. Click both the "Try the comparison" and "Single locus fingerprinting" buttons. The technique in this lab is old; newer, much better ones are used now.
You can learn about that by googling "CODIS." A good and very understandable article discussing the moral and legal implications of CODIS and other techniques which record our DNA sequences can be found here: http://www.backgroundcheck.org/how-secure-is-your-dna/, and a related article, here: http://www.the-scientist.com/?articles.view/articleNo/34006/title/Anonymity-Under-Threat/
Genetic Science Learning Center at the University of Utah

Concept Maps - These can be very useful, especially in studying biology and physiology. This site offers a free program that you can download for Windows that helps you to draw neat and legible concept maps.

Stephen L. Morgan at the University of South Carolina has written an excellent tutorial on the use of significant figures, which is available here: http://www.chem.sc.edu/faculty/morgan/resources/sigfigs/.

Gel electrophoresis is explained here: http://www.dnalc.org/resources/animations/gelelectrophoresis.html and PCR is explained very well by this animation: http://www.dnalc.org/resources/animations/pcr.html Finally, we can "put it together" to see how it all can be used to identify a criminal, a child, a parent, or anyone else! http://www.dnalc.org/view/15983-Today-s-DNA-profile.html All three animations are brought to you by the Dolan DNA Learning Center.
