Students are studying the different uses of DNA fingerprinting by participating in a mock Crime Scene Investigation. Students received police reports, collected DNA samples from the four suspects, and evaluated the DNA found at the crime scene. Students evaluated the base pairs, Adenine, Thymine, Guanine, and Cytosine, and charted their molecular weight to form a unique pattern of bands. These bands are used by police and investigators to assess the DNA evidence of victims, suspects, and perpetrators.

These photographs supplied by Genelex Corporation show several different examples of DNA fingerprints similar to those used in criminal investigations and paternity cases. In each photograph it is possible to match the genetic fingerprints of certain samples to those of other samples, such as in the case of crime scenes, paternity testing, and identical twins vs. non-identical twins.

Here is another article for my Forensic Science fans. This article explains how DNA is used by lawyers in court and gives samples of evidence collected from real crime scenes and compares the DNA found at the crime scene to that of the suspect.

This week, students are learning about DNA and its effects in the courtroom. Technological advances in DNA have revolutionized how crimes, paternity, diseases and other medical cases are studied. Tomorrow, students will try to find the guilty party in a mock crime scene by collecting and analyzing evidence. Attached is an article that may be of interest to some of you Forensic Science fans. The article, DNA On The Witness Stand, highlights the investigation into the real-life mass murder of 15,000 Argentineans during a period of political unrest in the 1970s.

There will be a test on Chapter Three on Friday, October 27th. As always, there is an optional study guide available that can be picked up in class. If completed and signed by a parent, the study guide is worth five bonus points. There will also be a morning review session on Friday morning at 8:15.

SAVE THE CELL!

When we began our Chia experiment, students designed an independent variable that would test the effect of light on the growth of a plant. Group C was locked in a dark cabinet for almost two weeks, with no exposure to sunlight. Most students predicted the Chias would not grow any hair at all, but when the cabinets were opened yesterday, students were in for a surprise! The Chias did grow hair, but because they were not exposed to sunlight, the chloroplasts were not able to effectively produce the green pigment chlorophyll. The result was yellow and white grass!
