Unit 2: DNA Analysis
Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
Curated OER
Who Is It?/Who Done It?
Students conduct an experiment that allows them to assess individual differences in random DNA sequences and apply those differences when solving a forensic problem. After discussing the polymerase chain reaction and its use to identify...

Who Ate The Cheese?!
In this crime scene investigation worksheet, students simulate DNA sequencing and DNA restriction analysis using paper strips of DNA. Students compare the crime scene DNA to the suspects and determine who is guilty.
Curated OER
Lost Tribes of Israel
Learners examine the issues involved with using DNA evidence in a courtroom trial. They read and discuss a case study of a particular trial, conduct research, and role-play a jury by reporting their verdict and discussing how they...

How Can We Extract Human DNA?
High schoolers perform an experiment in which they extract DNA samples from hair samples. They follow a set procedure to extract the DNA and complete summary questions.
Curated OER
Blood, I Presume?
Learners explain the value of blood in trials. In this DNA lesson students work together to collect and share information and ideas that they come up with after learning how to distinguish blood from other stains.
