Genetics and Biotechnology
The student will investigate the concepts of genetics and heredity, different
methods of reproduction, patterns of inheritance, and genetic disorders; as
well as, explore and evaluate the DNA technologies from both a scientific and
ethical perspective.
Lesson 5 - Investigate genetic engineering and DNA fingerprint technology.
Use the link “Create a DNA fingerprint” to explore this exciting new technology.
Don’t forget to print out a copy of the questions before you start.
DNA Fingerprinting
Create a DNA fingerprint
Students will learn the steps of DNA fingerprinting by creating a fingerprint in
a virtual lab. They will use this fingerprint to solve a virtual crime. The virtual
lab is interactive and goes through the step-by-step process of DNA
fingerprinting
Introduction:
1. DNA is unique for everyone. The only exception is if a person has what?
2. What are DNA fingerprints used for?
Part 1 “It Takes a Lickin”
3. What “crime” was committed?
4. What bodily fluid was removed from the “crime scene” to get DNA?
Part 2 “DNA Fingerprinting at the NOVA Lab”
5. What does a restriction enzyme do?
6. What is agarose gel?
7. What is electrophoresis?
8. Smaller fragments of DNA move ____________ than longer strands?
9. Why do you need to place a nylon membrane over the gel?
10. Probes attach themselves to __________
11. Which chemical in your “virtual lab” is radioactive?
12. Sketch your DNA fingerprint.
Use the following link to learn more about DNA technology, you should go through
three activities (out lined below) Use the next arrow at the bottom of the screen to
continue though the lesson.
Hands On DNA Fingerprinting
1.
The "Hey! You're Me!" button takes you to a story about two people who meet their
identical twin they never knew and turn to DNA Fingerprinting to find out if they really
are related. If you don't know much about DNA Fingerprinting start here!
2.
The "Tutorial" button takes you to the Tutorial, which allows you to interactively learn
about DNA Fingerprinting. This section is detailed, and assumes you know some
terminology to start with.
3.
The "Try It Out" button takes you to the "Try It Out" section of the Tutorial, where you
can gain some hands-on experience with some of the steps involved with DNA
Fingerprinting
