Forensics: DNA Evidence

This is my DNA Evidence lecture given in a forensics class about types of evidence that contain DNA.  It also describes Polymerase Chain Reaction (PCR) and DNA Fingerprinting by electrophoresis in detail.  There is also an embedded youtube video in the prezi and the powerpoint.  The content in the prezi and powerpoint are identical so it is just a matter of choice for the teacher.  Do you want to use the free prezi or purchase the powerpoint from my TPT store?

Topics include:

  • DNA Structure
  • Polymerase Chain Reaction
  • Gel Electrophoresis
  • DNA Fingerprinting
  • Types of DNA Evidence

The prezi above is available for free and there is a student note-guide available in my TPT store, plus a powerpoint version of the prezi if you prefer that format:

In Practice…

This lecture takes approximately 75 minutes depending on how much detail and examples are given.  It is good to use in a Forensics course in high school or introductory college level setting.  It includes a refresher section but most students  have had some introductory biology so they have been exposed to DNA structure and replication.

Biotechnology Lecture & Note Guide

BiotechCoverThis PowerPoint presentation and student note guide handout contains 29 slides introducing Biotechnology and an 11-page handout for students to fill in during the lecture. I have used it with Biology classes and Forensics classes. It includes the explanations of restriction enzymes, gel electrophoresis, PCR, recombinant DNA and transformation, genomics, and proteomics.
This presentation with class discussion would take 90 minutes or more in my classroom, depending on the depth of discussion. The student note guide is included as both an editable Word document and a PDF file. The powerpoint file is also editable!
