DNA from the Beginning (a 3CD set) is a multimedia primer on the basics of DNA, genes, and heredity. It is an ideal teaching tool for high school students and will also interest adults with a non-technical background who wish to learn more about the impact that DNA science is having on our lives.
The content in DNA from the Beginning is built on a progressive series of important but simply stated concepts such as Children resemble their parents. An understanding of the concept is then conveyed in clear,understandable terms with the aid of links to animations, photographs, and video clips, and biographies or interviews featuring key scientists. A wealth of other information and links to web resources are included. Problems and their solutions are included to allow teaching through self-examination.
Based on the award-winning web site, the DNA from the BeginningCDROM set provides over 72 hours of study time. It runs on Macintosh computers and PCs, and gives immediate access to all the online content, in attractive, uncluttered screens, without the need for network connections.
A must for high schools and junior colleges in conjunction with biology classes.
