Webquest: DNA and Forensic Science
INTRODUCTION
The first step is to learn about the
structure and function of DNA. The next step will be to look at
replication of DNA, transcription and translation. Once you understand the basics of DNA,
you will do virtual labs demonstrating how DNA fingerprints are made and read
and solve a mystery. The next step
you will do a virtual lab on Gel Electrophoresis.
