He was a government administrator in colonial India and began using fingerprints in July 1858 to identify illiterate prisoners and workers in India.
OBJECTIVE
SWBAT understand what CODIS provides to forensic scientists and investigators.
AGENDA
1. CODIS System2. FBI Brochure3. CODIS Simulation4. Exit Slip
CODIS
CODIS is the acronym for the “Combined DNA Index System” and is the generic term used to describe the FBI’s program of support for criminal justice DNA databases as well as the software used to run these databases.
The National DNA Index System or NDIS is considered one part of CODIS, the national level, containing the DNA profiles contributed by federal, state, and local participating forensic laboratories.
CODIS
The DNA profile also known as a DNA type is stored in the database.
For Forensic STR DNA analysis, the DNA profile consists of one or two alleles at the 13 CODIS Core Loci.
FBI BROCHURE
Log on to the Google Classroom Select the FBI Brochure Link Read through the information on this page –
you will have 10 minutes
CODIS SIMULATION
We will simulate a genotyping at one of the loci commonly used in forensic typing.
In reality, DNA profiling is performed at a number of different loci; the larger the number of loci profiled, the more powerful the ability to find a match.
EVERYONE STAND
There is an eyewitness who saw the criminal run from the crime scene and has provided a description.
CONNECTION
Adding more pieces of observation to a physical description of the escaping criminal made it more likely to identify the correct person.
In exactly the same way, adding more genetic loci to the DNA profiling profile makes in a much more powerful tool for solving crimes.
STR ALLELES AT 4 LOCI
VWA (blue) Chromosome 12 D8 (green) Chromosome 8 D5 (yellow) Chromosome 5 TH01 (red) Chromosome 11 Directions:
Need one student to be “mom” and one student to be “dad” and you will determine your genotype.
Everyone else will inherit your STR genotype by selecting at random one allele from each of Mom’s bags and one allele from each of Dad’s bags
Data is entered on the chart
RANDOM MATCH PROBABILITES
DISCUSSION QUESTIONS
EXIT SLIPOCTOBER 16, 2014
1. Get out a mobile device or use one of the computers and go to m.socrative.com. You can also use one of the iPads that has the Socrative app.
2. When prompted, enter 417101 for the room number.
QUESTION: What is the CODIS system and how is it used?
