BLAST Algorithm

Everyone loves a good mystery ... can your class actually solve one? Partnered pupils take on the role of forensic investigators during a three-part activity focusing on DNA evidence processing. Learners discover the methods used to...

Some experiments have changed society's general world view, and this video highlights three of them. Questionable methodologies used in these experiments still raise debate, but the results defined biology and led us to where we are today.

Explaining exactly how DNA works to provide genetic information is a complex topic, but it is presented in a clear and engaging way through a five-minute video. Have learners try to explain how DNA works before watching the video, then...

Students describe the structure of DNA and its components and can comprehend that real DNA and its cartoon representation are very different. They are able to link DNA to genetic make-up.

Young scholars study the process of DNA Fingerprinting and how DNA Fingerprinting is used in solving crimes. They examine a crime scenario that involves collecting DNA Fingerprinting information from blood collected at the crime scene....

Students explore DNA. They work in groups and mix prepared detergent/ salt solution, meat tenderizer solution, Fleischman's yeast and water to extract DNA from yeast. Observations are recorded.

Students are able to distinguish between transcription and replication. They are able to distinguish between DNA and RNA. Students name some of the proteins and enzymes used in replication and transcription. They are able comprehend the...

Students create a model of DNA and simulate replication with their models in an activity that uses licorice, colored marshmallows, and toothpicks. Students also label a diagram of replication and indicate major parts of the DNA molecule.

Learners describe the fundamentals of DNA such as structure and replication. Given a picture of a gel, they circle the band that represents the smallest DNA, the largest DNA, and show which DNA sources are the same.

Students discuss methods used by forensic scientists and the basics of DNA and how it can be used to identify an individual after reading an article from The New York Times.
