General Overview

Primer on Molecular Genetics -- html format

The Department of Energy's 44-page primer on basic molecular biology. Why DOE? Because they were among the first to get involved with the human genome project. The primer reflects that goal -- it is strongly slanted towards explaining the techniques behind the human genome project, but it does cover many standard techniques (in simple language) along the way.

Note that this article was written in 1992, so some of the information (e.g., the amount of DNA sequence available) is out of date.

Primer on Molecular Genetics -- pdf Same as above, as a downloadable PDF file (732 kilobytes). Printed versions of this file will be placed on reserve in Odegaard Library.
